摘要
目前,土的压缩模量被认为是一个近似常数的做法是不合理的。结合港珠澳大桥工程室内压缩试验成果,分析不同应力区间和不同应力路径下土的压缩模量变化规律,并分析不同条件下的压缩模量变化幅度,为土的变形计算参数取值提供参考。
It＇s unreasonable that the compression modulus is considered as an almost constant at present during the compression estimation and deformation calculation of soils. Combining the geotechnical test results in project of Hong Kong-Zhuhai-Macao bridge, we analyze the evolution law of compression modulus under loads＇ changing, and discuss the evolution range of compression modulus under different loads. It may serve as reference for deformation calculation parameters of soils.
