摘要
通过室内压缩固结实验,研究了不同应力水平对软土地基压缩性的影响,得出了软土地基的压缩系数、压缩模量、压缩指数、回弹指数等主要压缩指标随固结压力的变化规律,研究成果可为软土地基在路堤填土分级加载情况下固结沉降计算提供指导。
An experiment was conducted to study the effects of different stress level on compression and consolidation behaviors of swamps soft soil based on compression and consolidation experiments of swamp soft soil.Obtained of soft soil foundation compression coefficient,compression modulus,compression index,the springback index such main compressed indexes variation rules of consolidation pressure.The results can provide relevant parametes for the calculation of consolation settlement of highway soft soil foundation in swamps when graded load of embankment filling was adopted.
