摘要

在对位于加拿大安大略省西南部Walkerton附近的现有Greenock Creek大桥的桥梁更换/修复方案进行初步评估后,拆除现有上层建筑和再利用现有基础被选为首选方案。首选方案是基于甲板和上层建筑的状况调查,以及交通机动性、经济性、可持续性和环境优势。该决定表明了交通部(MTO)的承诺,即评估支持交通部倡议和运营需求的新技术和应用,特别是鼓励现有基础的再利用。现有的结构建于1971年,是一个单跨结构,承载着9号高速公路通过格林诺克溪。现有的桥台建立在H-Pile基础上,根据原始建筑合同图纸,长度约为8米,并以1:4和1:8的方式安装。场地的地下条件由粘土粉砂到粉砂和砾石下垫的粉砂组成。地下水位位于或接近地表。底土的相对密度在地表3 ~ 5米处从松散到致密,在这些深度以下变得非常致密。本文介绍了现有HP310x79 h型钢桩的承载力、完整性和耐久性评价过程。规划、组织和实施了一项综合方案,其中包括勘探钻孔以验证地下条件,检索土壤样本以确定桩周围土壤和地下水的腐蚀性,以评估腐蚀程度,以及包括平行地震和钻孔磁力计测试在内的地球物理测试,以估计现有钢桩的嵌入长度。本次调查的结果被用来评估现有的钢桩基础是否能够承受新的上层建筑荷载再持续75年。

Reuse of existing steel pile foundations – Greenock Creek Bridge, Walkerton, Ontario, Canada
Following a preliminary assessment of bridge replacement/rehabilitation options for the existing Greenock Creek Bridge located near Walkerton in Southwestern Ontario, Canada, the removal of the existing superstructure and the reuse of the existing foundations was selected as the preferred option. The preferred alternative was based on condition survey of the deck and superstructure and traffic mobility, economic, sustainability and environmental advantages. The decision is demonstrative of the Ministry of Transportation’s (MTO) commitment to assess new technologies and applications that support Ministry initiatives and operational needs and specifically to encourage the reuse of existing foundations. The existing structure, built in 1971, is a single span structure that carries Hwy 9 over Greenock Creek. The existing abutments are founded on H-Pile foundations that according to the original construction contract drawings are approximately 8 metres in length and installed at 1:4 and 1:8 batters. The subsurface conditions at the site consist of clayey silt to silt underlain by silty sand with gravel. The groundwater table is at or near the ground surface. The relative density of the subsoils is loose to dense in the surficial 3 to 5 metres and becoming very dense below these depths. This paper describes the process of evaluation of the capacity, integrity and durability of the existing steel HP310x79 H-piles. A comprehensive programme was planned, organized, and implemented that included exploratory boreholes to verify the subsurface conditions, retrieval of soil samples to determine the corrosivity of the soil and groundwater around the piles in order to assess the degree of corrosivity and geophysical testing including parallel seismic and borehole magnetometer testing to estimate the embedment lengths of the existing steel piles. The results of this investigation were used to assess if the existing steel pile foundations can carry the new superstructure loads for another 75 years.
