水盐含量及电阻率对盐渍土抗剪强度的影响
Effects of water salt content and resistivity on shear strength of saline soil
摘要
Abstract
This paper is aimed at an investigation of the effects of water and salt content and resistivi-ty on the shear strength of saline soil.The experiment conducts a laboratory tests on saline soil in Changling County by measuring the moisture content,salt content,resistivity and shear strength of the soil at different depth to study the relationship among these factors.The results show that the resistivity of saline soil gradually decreases with the increase of salt and moisture content.The triaxial shear test shows that the internal friction angle and cohesion decrease with the increase of salt content,which is negatively correlated with the moisture content.The good linear relationship exists between the shear strength and resistivity of saline soil,and the shear strength increases gradually with the increase of resistivity.This fitting formular built up on the shear strength of saline soil and resistivity could provide a reference for practical engineering application.关键词
