摘要
长沙市轨道交通1号线一期工程KC-1标段营盘路站-五一广场站区间南段岩溶发育,为了详细查明该段岩溶发育情况,通过电磁波CT、地震映像法等物探方法在该工程中的使用,结合钻探成果综合分析了岩溶空间分布情况,合理减少了钻探工作量,为后期盾构机选型及施工方案提供了依据。
The karst development in the southern section of the Yingpan Road Station-Wuyi Square Station section of the KC-1 section of the first phase of the Changsha Rail Transit Line 1 project.In order to find out the karst development in this section in detail,geophysical prospecting methods such as electromagnetic wave CT and seismic imaging are used,the use of this project,combined with the drilling results,comprehensively analyzed the spatial distribution of karsts,reasonably reduced the drilling workload,and provided a basis for the selection of the shield machine and the construction plan in the later period.
