Support system design has always been a critical engineering problem for large-scale tunnels excavated within fault zones. In fault zones, it is possible to encounter face and ceiling stability problems encountered during the tunnel excavation in the short term and failures in the support systems due to squeezing in the long term. For this reason, when designing support systems, short-term and long-term parameters should be considered. The most important factors in selecting the support system to be installed are to describe the geological conditions well and the correct selection of geotechnical design parameters.

断层带大型隧道的支护系统设计一直是关键的工程问题。在断裂带中，短期内可能会遇到巷道开挖过程中遇到的工作面和顶板稳定问题，长期内可能会遇到支护系统因挤压而失效的问题。因此，在设计支护系统时，应同时考虑短期参数和长期参数。在选择安装支护系统时，最重要的因素是地质条件的描述和岩土设计参数的正确选择。因此，本研究的主要目的是调查Yazışma yazaryi / Correspondence: cgokce@hacettepe.edu.tr Jeoloji Mühendisliği Dergisi / Journal of Geological Engineering 45 (2021) 1-28 DOI 10.24232/jmd.935374安卡拉2 Hacettepe Üniversitesi, Jeoloji Mühendisliği Bölümü， Beytepe，安卡拉gelikan(收稿):30 Ağustos(2020年8月)，d zeltme(修订):21 eyl l(2020年9月)，喀布尔(收稿):T36隧道全长4100 m，最大覆盖层厚度180 m下已完成开挖及支护工作。在断裂带过渡区，在覆盖层厚度为115 m的情况下进行支护，短期面临工作面稳定问题，长期面临巷道挤压问题。本文讨论了隧道变形对隧道短期和长期影响的原因，并对数值分析和支护系统进行了研究。此外，还讨论了隧道施工中最重要的问题之一——断裂带穿越准则。

Quantitative estimations of climate changes on hydrological processes help to understand and manage water resource problems such as floods and droughts in the future. This study aims to present the preliminary results of a study to determine the impact of climate change on river flow to develop sustainable watershed management plans and to evaluate the possible urban water use and environmental impacts to prepare policies to mitigate its negative impacts. In this study, the Soil and Water Assessment Tool (SWAT) was used as a hydrological model to predict hydrological effects of climate change to better understand and solve future water resource problems. In this context, firstly the Soil and Water Assessment Tool (SWAT) was operated on the Yuvacık Dam Basin in Marmara Region to reveal the present hydrological situation. The hydrological model was then simulated by using the climate change data that have 20 km spatial resolution between 2021-2099 years based on RCP 4.5 and RCP 8.5 scenarios that were produced by the General Directorate of Meteorology. Thus, the effects of climate change on the amount of water and sediment were estimated between these years. According to the RCP 4.5 and RCP 8.5 scenarios, 2.23% and 2.062% decrease in the average annual rainfall, and 1.24 and 0.03 of increase in temperature values were predicted, respectively. However, an increase in precipitation was expected between April and August. The average monthly flows (between 2006-2014) of the Kazandere, Kirazdere and Serindere rivers recharging the Yuvacık Dam in the basin is 0.55, 1.28 and 1.94 m3/s, respectively. Corresponding modelled flow values based on RCP 4.5 and RCP 8.5 scenarios for 2021-2099 period, for Kazandere, Kirazdere and Serindere are 0.14 and 0.17 m3/s, 0.41 and 0.33 m3/s, 0.86 and 0.68 m3/s, respectively. These values show significant decrease in flow rates of the rivers in the future. Moreover, the peak flow values of the streams especially for Kazandere and Kirazdere decrease from 8 to 2 m3/sec. The amount of the monthly average of sediment measured at the Serindere stream station for the years 2010-2013 was 49 tons, while it was calculated as 247.58 tons based on RCP 4.5 and 332.21 tons based on RCP 8.5 for 2021-2099 period. According to both scenarios, an increase in the predicted rainfall between April and August, and an increase in temperature will cause mechanical erosion in the basin. Thus, the amount of sediment carried by flow is expected to increase. The Yuvacık Dam is used for providing irrigation and drinking water requirements of Sakarya and Izmit provinces, and for the prevention of flood as well as for water management during drought periods. Therefore, the decrease in the flow rates of the streams recharging the dam will cause a decrease in the water volume of the dam, hence the future water management planning should be made for the crop pattern in the irrigated areas of the dam and for the drinking water usage.

Many developed and developing countries use rail systems in addition to road systems in public transportation. One of the most frequently used types of these rail systems is the light rail systems (LRS). The routes of the LRS are generally preferred on the existing road route. This situation creates some problems in terms of ground conditions. Since the rail system vehicle weights and passenger capacities are much more than road vehicles, the loads they apply to the ground are also higher. However, deformations occurring on the road surface generally affect vehicles and passengers in terms of comfort, while small deformations on rail systems can bring major problems such as accidents and deaths. For this purpose, it is very important to investigate the ground structure of the rail system route and to analyze the suitability situation in order to prevent these problems. In this study, the suitability of the LRS route planned to be built in the city center of Erzurum in terms of physical properties of soil was analyzed. In the analysis, it was suggested that some locations were problematic in the results obtained by using the basic rotary Erzurum İli Hafif Raylı Sistem Güzergahının Zemin Emniyeti Açısından Yeterliliğinin Araştırılması Investigation of Adequacy of Light Rail Systems Route in Erzurum Province in Terms of Ground Safety Ömer Lütfü AYDIN1 , Emre KUŞKAPAN2* , Muhammed Yasin ÇODUR2 1 Erzurum Büyükşehir Belediyesi, Muratpaşa Mah.

许多发达国家和发展中国家在公共交通中除了公路系统外还使用铁路系统。这些轨道系统中最常用的类型之一是轻轨系统(LRS)。在现有的道路路线上，LRS的路线通常是首选的。这种情况在地面条件方面造成了一些问题。由于铁路系统的车辆重量和载客量远远超过公路车辆，因此它们对地面施加的载荷也更高。然而，路面发生的变形通常会影响车辆和乘客的舒适度，而铁路系统的微小变形则会带来事故和死亡等重大问题。为此，对轨道交通线路的地面结构进行调查，分析其适宜性，是防止这些问题发生的重要手段。在本研究中，从土壤物理性质方面分析了计划在埃尔祖鲁姆市中心建设的LRS路线的适宜性。默克尔齐Yönetim加拿大。Yakutiye, Erzurum 2 Erzurum Teknik Üniversitesi, m hendislik ve Mimarlık fak ltesi， İnşaat Mühendisliği Bölümü， Erzurum geliu(已收):05 Temmuz(7月)2020 / d zeltme(修订):26 Ağustos(8月)2020 /喀布尔(已收):在地面条件不适宜的情况下，我们会考虑乘客的需求，开辟另一条路线。

670 pillar is a geological barrier that will trap the rock blocks falling and rolling from the deformation zone of the Eynez fault as well as to prevent the materials belonging to the landslides to be formed along the fault zone from reaching the coal production area. It forms the foot wall of Soma-Eynez fault and consists of Neogene aged marls. The toppling failures observed in the 670-pillar ́s slopes threatened the safety of excavation works for coal production in the open pit. The maximum runout distances of rock fragments that had toppled, fallen and rolled at different slope heights as a result of the mentioned mass movements were determined using computer softwares. The project excavation limit for the open pit coal mine was determined by considering the runout distances calculated for different slope heights. In this work, toppling failures observed in the 670-pillar ́s slopes were investigated both Soma-Eynez Fayının Düşen Bloğunda (670-Topuğu) Yeralan Bir Açık Ocak Kömür Madenindeki Gözlenen Devrilme Yenilmelerinin İncelenmesi Investigation of Toppling Failures in an Open Pit Coal Mine Located in the Foot Wall of Eynez Fault-Soma (670-Pillar) Batuhan TERLİ1 , Enes KALHAN1 , M.

Safety factors obtained from different softwares for the same slope geometries were compared and the effect of friction angle (ɸ) and cohesion (c) values of the joint surfaces on safety factor that cause toppling failures were investigated. In addition, the time-dependent changes of joint aperture increase rate obtained from 20-deformation measurement points installed on the cracks causing toppling failures were investigated. The areas where the joint aperture increase rate is highest and the areas where the toppling failure is observed in the pillar ́s slope were associated.","PeriodicalId":35316,"journal":{"name":"Jeoloji Muhendisligi Dergisi","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68808277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
