摘　　要：传统一维沉降固结理论,将沉降固结参数假设为常量,影响了计算的准确性和精度。文中以西安地区的粉质黄土为例,进行了固结试验,研究了沉降速率的变化规律与饱和土压缩系数及压缩模量随不同有效应力、孔隙比的变化规律。Settlement consolidation parameter is assumed as a constant in traditional one-dimensional theory of settlement consolidation,which influences calculation accuracy and precision.This paper carries out consolidation test on silty loess in Xi＇an area to study the change rule of settlement rate and that of saturated soil compression coefficient and compression modulus with effective stress and void ratio.

关 键 词：粉质黄土 固结 沉降速率 压缩系数 压缩模量
