摘要
总结了北京地区土岩复合地层(含基岩隆起)的分布及岩土相关特性,针对不同施工工法的特点,全面分析了明挖法、矿山法及盾构法遇土岩复合地层中施工时可能产生的各类安全风险,从勘察、设计、施工、监测及应急方面提出了针对性的安全风险管控措施,给出了具体工程案例,为地铁工程安全建设提供支撑。
This paper summarizes the distribution and related geotechnical characteristics of soil-rock composite(including bedrock uplift)strata in Beijing.According to various specific risk issues during construction in the bedrock uplift stratum,this paper puts forward some cases and targeted safety risk control measures from five aspects of survey,design,construction,monitoring and emergency response,which provides support for the safe construction of subway projects.
