| 摘 要： | 盐渍土在浸水后由于盐分的溶解,对土体的强度产生较大的影响。在以往的研究中,主要以饱和与非饱和土体的强度比较来说明水对强度的影响,没有研究在部分浸水后土体的变形和强度的变化规律。针对这一点,在参考黄土增湿剪切方法的基础上研究了盐渍土的增湿剪切变形特性,探讨了垂直压力、干密度和剪应力水平对剪切变形量的影响规律。

| Abstract: | Saline soil in the water has a greater impact on the soil strength owning to the salt dissolved.Previous studies are focused on the effect of the saturated and unsaturated soil strength,and not research the changes of soil deformation and strength with part of the water.In this paper,based on the moistening shear test of loess,study on the moistening shear characteristic of aline soil and the influence facters to deformation,including conslidation pressure,drying density and shear stress ratio are carried o... |
