地铁盾构区间岩溶处治施工技术要点

Key Points of Karst Treatment Construction Technology in Subway Shield Section

随着城市地下交通建设的迅速发展,地铁盾构隧道施工经历岩溶区域成为常见挑战。文章以深圳地铁16号线龙城中路站至龙平路站区间为例,探讨了岩溶地带盾构隧道施工处理实例,并研究了施工方案,阐述了溶洞注浆处理施工技术、盾构掘进溶洞段处理措施等,为类似地质环境下的地铁建设提供了有力参考。

With the rapid development of urban underground transportation construction,the construction of subway shield tunnel in karst areas has become a common challenge.Taking the section between Longcheng Middle Road Station and Longping Road Station on Shenzhen Metro Line 16 as an example,this paper discusses the construction treatment example of shield tunnel in karst areas,studies the construction scheme,expounds the construction technology of karst cave grouting treatment and the treatment measures of shield tunneling karst cave section,which provides a strong reference for subway construction in similar geological environment.
