摘要
岩溶发育区盾构法施工一直是地铁施工过程中的一大难题,盾构在穿越岩溶区过程中经常出现盾构机栽头、刀具异常损坏及岩溶水压过大导致喷涌等问题。文章依托深圳地铁14号线大运站—1#风井区间穿越多个岩溶发育区的实际工程案例,对岩溶发育区盾构施工技术进行探讨。
The shield method construction in karst development areas has always been a big problem in the process of subway construction,and problems such as declination of the shield machine head,abnormal damage of the cutters,gushing caused due to excessive karst water pressure,etc.,are often encountered during the process of shields passing through karst areas.In this article,based on the practical engineering case of passing through multiple karst development areas in the Shenzhen metro line 14 Dayun station-1#ventilation well section,the shield construction technologies in karst development areas are discussed.
