浅谈软土地基设计的一般方法

The General Method of Soft Land Base Design

由于软土地基的低承载力、压缩性高、透水性差、结构触变性等特殊的工程特性 ,因此软土地基设计的好坏成为工程安全的关键。本文在传统土地设计的基础上 ,强调了上部结构、基础、地基共同作用的重要性 ,把软土地基设计概括为“一个中心、一个目的、两个基本点、六个步骤”,同时就设计参数取值和计算理论进行了讨论 。

Because of the special project properties of the soft land base like low bearing force,high compressibility,bad water permeability and structure touching denaturation,the quality of the soft land base design becomes the key of the project safety. On the basis of the traditional land design, this paper emphasizes the importance of the common effect of top structure, base and foundation, generalizes the soft land base design to “ a center, a purpose, two basic points and six steps”,and, at the same time, discusses value-taking of design parameter and calculation theory for the soft land base design in the future.
