真空预压侧向位移预估及控制效果分析

Analysis of Lateral Movement and Control Effect about Vacuum Preloading Based on Settlement Estimating

针对真空预压侧向位移控制的问题,研究了以预压地基沉降量反算地基力学参数,并以反算参数进行数值模拟的方法。在地基沉降量一致的情况下,该法可有效的模拟预压地基处理期间的侧向影响范围,并为侧向位移控制措施的采取提供指导,有效的保证工程的安全顺利实施。

Aiming at the lateral movement problem of vacuum preloading,research the method of back calculation mechanical parameter based on settlement of preloading foundation,and then conduct numerical simulation based on this parameter.In the case of settlement is equal,this method can effective simulation the lateral effect area in the course of ground treatment,and offer guidance for control measurement of lateral movement,guarantee the engineering carry out smooth and safety.
