摘要
在综合分析太原地铁2号线建设场地地形地貌、地质构造、地层岩性、水文地质条件的基础上,阐述了太原地铁工程建设中所面临的砂土液化、高地下水位、深基坑开挖与支护等诸多岩土工程问题。通过总结类似工程施工技术和经验,提出了能够有效解决太原地铁工程建设所面临岩土工程问题的施工建议和对策。
Based on the comprehensive analysis of the natural topography, geological structure, lithology, and hydrogeology in the site of No. 2 line of Taiyuan Metro, the paper describes the main geotechnical problems which could occur in the con- struction of the metro, such as sand liquefaction, high groundwater level, excavation and supporting of deep foundation pit and so on. Meanwhile, through the summary of the technique and the experience of similar projects, the paper proposes some effective suggestions and countermeasures for solving the geotechnical problems faced by the construction of No. 2 line of Taiyuan metro.
