摘要

软土一般具有结构性，试验表明，加荷比会对结构性软土压缩特性有很大的影响，加荷比增加土体剪切趋势，降低土体结构强度，使土体的结构屈服应力值和压缩指数降低。在试验的基础上，给出了考虑加荷比影响的结构性软土地基的沉降计算方法。工程算例表明，在加载终值相同的情况下，如果加荷比过大，就会增大结构性软土地基沉降产生附加沉降，为了减小对软土结构性的破坏而影响土体压缩特性，建议对结构性软土的加荷比不宜采用为1:1以上，宜采用1:0.25或1:0.5。

Abstract

Most natural clays have structural property; the experiments show that the influence of loading ratio on the settlement property of the structured soft clay is notable. The loading ratio increases the shearing trend in soft clay

which depress structure strength

structure yield stress and compression index. Based on the experiment

soft clay settlement calculation method considering influence of loading ratio is presented. The examples show that the bigger loading ratio in the course of loading enlarges settlement of structured soft clay ground. For the sake of reducing the influence of loading ratio on settlement property

it is suggested that the loading ratio of structured soft clay 1:0.25 or 1:0.5 should be adopted. If the loading ratio of structured soft clay is bigger than 1:1

it is not suitable.
