真空预压法地基处理影响范围分析

Analysis of Affected Area for Foundation Treatment by Using Vacuum Preloading Method

针对真空预压软土地基处理施工过程中,由于场地沉降造成周边建筑物、构筑物开裂等常见问题,结合工程实例,对比实测数据和有限元软件计算结果,分析计算软土地基中沉降、位移、孔隙水压力的变化规律及其对周围环境的影响情况,为真空预压法在软土地区的进一步推广应用提供了理论依据。

In the construction of soft base treatment by using vacuum preloading method,the settlement causes the cracks of surrounding structures and buildings.Based on engineering practice,the real-measured data are compared with the calculation results by using finite element software in order to calculate and analyze the change rules for the settlement,displacement,pore water pressure of soft base as well as the impact on the surrounding environment.The results will provide a theoretical basis for further application of vacuum preloading method in soft soil area.
