Abstract

Climate warming has affected the transportation infrastructure in Nunavik, Quebec, Canada. Heat drain is an innovative heat extraction technique using density-driven convection of the pore air in the geocomposite of the heat drain to cool the ground during winter. This paper examines the thermal conditions of the road embankment including a heat drain installed in the shoulder at Salluit, Nunavik, Quebec, Canada. Following the installation of the heat drain, a decrease of the soil temperatures was observed. A 2-D finite element geothermal model was developed to reproduce the thermal regime underneath the heat drain, based on the site condition at Salluit. Field measurement of ground temperature for the four year monitoring period from 2012 to 2016, were used to calibrate the model. After the calibration, the long-term climate warming effects on the ground thermal regime was investigated using the model developed.

加拿大哈德逊海峡海岸附近路堤下的热排水系统的热性能

气候变暖对加拿大魁北克努纳维克的交通基础设施造成了影响。热排水管是一种创新的热提取技术，利用热排水管土工复合材料中孔隙空气的密度驱动对流，在冬季冷却地面。本文研究了加拿大魁北克省努纳维克萨卢伊特路肩路堤（包括安装在路肩的排热管）的热状况。安装排热系统后，土壤温度有所下降。根据 Salluit 的现场条件，开发了一个二维有限元地热模型，以再现排热管下方的热机制。在 2012 年至 2016 年的四年监测期内，对地温进行了实地测量，用于校准模型。校准后，使用所开发的模型研究了长期气候变暖对地热机制的影响。

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
