摘　　要：结合天津港新近吹填区的码头工程案例,根据码头陆域真空预压施工期间的实时监测数据,分析真空预压施工中各工序对岸坡土体的变形影响。研究结果表明陆域真空预压施工有利于提高岸坡的稳定性,合理安排真空预压的施工顺序能最大限度地降低软土地区因真空预压施工导致岸坡失稳的风险,可供同类地基加固工程参考。Based on a wharf project in new dredger filled zone at Tianjin Port, the real-time monitoring data on land vacuum preloading construction are studied to analyze the influence of different vacuum preloading processes on bank soil deformation. The research results show that land vacuum preloading may improve the bank stability. Therefore, to arrange reasonable vacuum preloading process may minimize the risk of bank destabilization caused by soft soil vacuum preloading construction, which will provide references for similar foundation reinforcing projects.
