摘　　要：以某综合交通枢纽的地下通道施工为例,通过技术优化和采用加固措施顺利完成了在浅覆土运营地铁上方的箱涵顶进施工。介绍其抗拔桩隔离、管幕保护和门式注浆等加固措施,以及箱涵顶进过程中的质量与安全控制,可为类似工程施工提供借鉴。Taking the construction of an underground passage of an integrated transportation hub as an example,the jacking construction of the box culvert above the subway in operation with shallow covering soil was successfully completed by optimizing techniques and using reinforcement measures.The reinforcement measures such as uplift pile isolation,pipe and curtain protection and door-type grouting,as well as the quality and safety control during the process of box culvert jacking were introduced,which could provide reference for similar engineering construction.
