摘要
武汉某明挖地铁车站岩溶发育强烈，采用物探、钻探等综合手段，查明岩溶分布特性。根据溶洞发育规模及与车站关系确定处理原则，根据溶洞充填情况确定处理方案。在地连墙施工前，对基坑内溶洞进行注浆（填石）处理，降低施工风险，确保施工和运营安全。
Abstract
The karst development at a Wuhan open-cut subway station is strong. Geophysical prospecting, drilling are used to find out the karst distribution characteristics. The principles (as well as the specific treatment solutions determined by the cave filling situation and development characteristics of karst water) of dealing with it are worked out based on the development of the karst scale and relationship between the karst and the station, Karst cave grouting in the foundation pit must be completed before the construction of underground continuous wall, which will reduce the construction risk of the subway station.
