摘要
基于温州某真空预压加固软土地基项目,进行了真空预压现场试验,分别对试验区的地基沉降、水平位移、真空度和孔隙水压力等指标进行跟踪监测,并对监测的主要成果进行分析评价。同时利用ABAQUS有限元软件,采用平面应变模型,对该真空预压现场试验进行了数值建模分析,计算结果与实测结果吻合较好,验证了基于ABAQUS有限元软件的数值计算方法在真空预压工程应用中的可靠性与适用性,可以为今后类似的真空预压工程的设计以及数值计算研究等提供参考。
This paper conducted field test based on a soft soil foundation reinforcement project by vacuum preloading method in Wenzhou,and the variation rule of surface settlement,horizontal displacement,vacuum degree and pore-pressure were monitored and studied in the process of vacuum preloading.Then,a finite element calculation in ABAQUS software has been performed to simulate the field test with plane strain model.The reliability and applicability of the numerical model was verified by comparison of the simulation and the corresponding results,it could be applied in the design and numerical calculation of similar vacuum preloading projects.
