摘要
文中介绍了真空预压法的基本原理,采用弹塑性本构模型进行计算分析,使用Marc的单元"生死"功能来模拟土体开挖和加压施工。利用真空预压法原理,通过一实例的有限元法分析了真空预压法在深基坑开挖支护中的可行性。
This paper introduces the basic principle of vacuum preloading method, carries out calculation and analysis with elastic plastic constitutive model and simulates soil excavation and pressurized construction with the element active/kill function of Marc. With vacuum preloading principle, through finite element analysis of an example, it analyzes the feasibility of vacuum preloading method in deep foundation pit excavation and support.
