摘　　要：以后世博地下空间开发工程博成路地下通道施工为例,采用全方位高压喷射工法(MJS),在运营中的共同沟两侧及底部成功实施加固,解决既有大断面共同沟穿越通道围护结构,导致围护结构不能封闭的难题。实践证明,MJS工法桩作为地基加固的一种方法,在大直径封闭围护结构及贴近共同沟的加固方面均具有较为可靠及安全的作用。Taking Bocheng Rd. underground passageway construction of underground space development in the after-Expo Area for example, MJS method is adopted in strengthening the both sides & the bottom of the operating common tunnel in this project, which can solve the problem, the enclosing structure cannot be sealed because of the existed large cross section crossing passageway. The practices prove that as a foundation strengthening method, MJS method is reliable and safe in large diameter sealed enclosing structure and adjacent common tunnel strengthening.
