摘　　要：随着城市建设的快速发展,轨道交通和地下空间开发无疑成为解决城市地面交通拥堵的最有效方法.然而,在岩溶地区,大规模的轨道交通建设中经常会遇到溶洞等岩溶地质灾害.岩溶分布的未知性和不规则性常常给轨道交通设计与施工建设带来困难.该文结合岩溶发育机理和岩溶勘察常规手段,分析和总结了岩溶地区可能引发的工程地质问题,以某市轨道交通3号线一期工程为例,采用高密度电法和地震映像法,结合工程地质钻探,查明了岩溶发育情况,为后期处理提供了依据.该文可对后续轨道交通工程及类似工程方案设计提供参考.With the rapid development of urban construction,the rail transit and underground space development undoubtedly become the most effective way to solve urban ground traffic congestion. However,the karst geological hazards such as karst caves are often encountered in large-scale rail transit construction in karst areas. The unknown and irregular distribution of karst often bring difficulties to the design and construction of rail transit. Combined with the mechanism of karst development and the conventional means of karst exploration,this paper analyses and summarizes the engineering geological problems that may be arised in karst areas. Taking the first phase project of an urban rail transit line 3 as an example,using high density electrical method and seismic imaging method,combining with engineering geological drilling,the karst development situation is identified,which provides a basis for later treatment. This paper can provide reference for the follow-up rail transit project and similar project design.
