真空预压方法是一种加固软土地基的新技术,在我国的软基加固工程实践中已有成功的应用,但其设计计算理论及力法落后于工程实践,尚处在探索和建立之中。本文对:一、真空预压之下软土地基的固结压密科算;二、加固后软土地基的允许承载力计算;三、加固后地基土在荷载作用下的沉降计算等三个问题作分析论述,这是进行合理的真空预压加固软土地基设计所必须解决的问题。
Vacuum preloading method is a new technology to reinforce soft soil foundation, which has been successfully applied in the practice of soft foundation reinforcement in China. However, its design calculation theory and method are lagging behind engineering practice, and it is still under exploration and establishment in. This paper is on: 1. Computation and calculation of consolidation of soft soil foundation under vacuum preloading; 2. Calculation of allowable bearing capacity of soft soil foundation after consolidation; 3. Calculation of settlement of subsoil under load after consolidation The problem is analyzed and discussed, which is a problem that must be solved to carry out reasonable vacuum preloading consolidation of soft soil foundation design.
