摘　　要：明挖法和暗挖法在施工时均会破坏原有的地质结构,导致地表下沉,因此,文中提出了地铁车站基坑支护中盖挖半逆作法施工技术,并以实际工程为例,对盖挖半逆作法、明挖法和暗挖法这三种施工方法的地表下沉情况进行试验测试,结果表明,盖挖半逆作法地表下沉量最小,提高了基坑的安全性和稳定性。Open excavation method and dark excavation method will destroy the original geological structure during construction,leading to surface subsidence.Therefore,the semi-reverse construction technology of digging the middle cover of the foundation pit support of the subway station is put forward.The project overview is intorduced,and the surface subsidence of the three construction methods,open excavation method and dark excavation method is tested.The experimental results show that the surface subsidence of the semie-xcavation method is the minimum,which improves the safety and stability of the foundation pit.
