摘要
由于隐伏岩溶发育的复杂性,局部位置的无规律性,勘察时又很难准确查清岩溶发育的空间分布特征,对地铁建设设计施工带来很多不利因素。文中介绍了广州地铁9号线沿线工程地质概况、岩溶发育特征及水文地质地征,对该线隧道施工的各种工法在隐伏岩溶区的工程问题进行了分析研究,并讨论了岩溶对地铁建设的不良影响和工程对策。
Due to the complexity and haphazard distribution of covered karst development,it is difficult to identify the spatial distribution of karst accurately,it will cause a lot of problem in design and construction of subway construction.This article describes geology,karst features and hydro-geological characteristics of the Guangzhou Metro Line 9 project,analysed the engineering problem of variety construction method in karst area of Metro Line 9,and discussed the karst's adverse effects of subway construction and engineering countermeasures.
