摘要
结合某轨道交通工程实例,描述了广州石炭系中、上统壶天群地层溶洞、土洞强烈发育地区某特大型土洞的分布、位置、尺寸等,并分析了该土洞对基坑开挖及主体结构施工的影响,提出可靠的治理方案,为岩溶地区工程处理提供参考。
Through example of urban rail transit engineering,we describe the distribution and dimension of a extra big cave in Guangzhou carboniferous karst area where the rock and soil cave have been strongly developed. We also analysis the influence of this cave for the sub- way station deep foundation and construction structure,and put forward the security engineering treatment for this cave. It give a good example for the engineering treatment for Carboniferous karst area.
