城市轨道交通线网规划中的岩土工程分析——以成都地铁2号线一期工程东段为例

在城市轨道交通线网规划中,岩土工程分析是一重要环节.作者以成都地铁2号线一期工程东段为例,进行了岩土工程分析.该地铁段设计全长约13.30 km,沿线设计11个车站和12段区间隧道,工程地质条件、水文地质条件及周边环境复杂.通过对该段的自然地形地貌、地层岩性、区域地质构造、稳定性以及岷江水系Ⅰ、Ⅱ级阶地的地质环境、所在地铁站点的岩土工程特性进行全面勘察和综合分析,为地铁工程的规划建设提供了施工建议和对策.

Geotechnical Engineering Analysis for Planning of No.2 Chengdu Metro Line

The eastern section of Chengdu Metro Line 2 project is 13.30 km,and has 11 stations and 12 interval tunnel engineering.Its geological conditions,hydrology geological conditions and the surrounding environment are very complex.According to the natural topography,lithology,regional geological structure,and stability of the geotechnical characteristics of the eastern section of the project of No.2 Chengdu Metro Line,comprehensive investigation and comprehensive analysis on geotechnical engineering characteristics were conducted,especially on geotechnical engineering characteristics of the Minjiang River system I and II order level.Finally,engineering advices were provided and applied in the scientific planning and construction of the subway project design for No.2 Chengdu Metro Line.
