摘要
贵阳城市轨道交通工程以地下线为主,少量高架线及地面线,施工中存在的主要岩土工程问题有:围岩稳定问题,涌水突泥问题,隐伏岩溶问题,地面塌陷问题,明挖基坑的边坡稳定、基坑涌水及岩溶地基稳定问题,桩基及高回填地基稳定问题等。结合工程实践,从暗挖隧道、明挖基坑、桩基及高回填地基这3种形式入手,对贵阳城市轨道交通建设施工中的存在的主要岩土工程问题进行了探讨,并提出了针对性的处理措施。
The urban rail transit projects in Guiyang City are dominated by underground lines with a few elevated lines and ground lines. The main geotechnical engineering problems in project construction include the stability of surrounding rock,water inrush and mud inrush,hidden karst,ground subsidence,pile foundation and high backfill foundation stability and the slope stability,foundation pit water inflow and karst foundation stability of open excavated foundation pit. In combination with engineering practices,the major geotechnical engineering problems in the construction of Guiyang urban rail transit project are discussed from three structure forms of open excavated tunnel,open excavated foundation pit and pile foundation and high backfill foundation,and the targeted treatment measures are also proposed.
