摘　　要：通过工程实际运用,探讨在施工场地狭小、施工净空有限、周边环境复杂的情况下,采用MJS工法的施工工艺。阐述在施工期间对地内压力进行严格控制,使周边土体位移、围护桩变形和管线的沉降监测均小于规范要求的警戒值。可供同类工程参考。Through an engineering practice,the construction technology of MJS method is adopted under the conditions of narrow construction site,limited construction clearance and complex surrounding environment.During the construction period,controlling the inner pressure strictly can ensure the displacement of surrounding soil,retaining pile deformation and the settlement of pipeline alert value be less than the standard requirements,which may provide a reference for the similar projects.
