在外荷载作用下,换填垫层法处理的软土地基不仅受到周边软土体侧向约束作用,而且具有明显的双层地基应力分布特征,因此当换填垫层的厚度超过基础宽度的0.5倍时,采用传统的扩散角法设计,明显偏于保守.本文从上述两方面着手,结合工程实例,论述换填垫层设计的经济性与安全性.
- Abstract:
-
Under the action of the external load, the cushion foundation is affected by lateral restraint from peripheral soft soil. Moreover, it has an obvious characteristic, that is to say, the stress distribution of twolayer foundation. So, it is quite conservative to use the traditional design method of dispersion angle when the thickness of cushion is 0.5 times wider than the width of foundation.The study on economy and security of the cushion design is based on these two aspects and engineering example.
