海相淤泥质土力学参数的实验研究

Experimental Study of the Mechanical Parameter of Marine Ooze Soil

实验通过对辽宁省丹东市海洋红村近海地区淤泥质粘土进行不固结不排水快速直接剪切试验,来测定此地区近海淤泥质土在不同含水率情况下的抗剪强度变化情况,通过计算提供本地区近海地基强度及地基稳定性计算所用的指标:淤泥质土层的黏聚力c及内摩擦角φ。进一步验证在不同含水率情况下淤泥质粘土的c、φ值呈何种变化规律。

By operating the unconsolidated-undrained quick direct shear test of the ooze cohesive soilalong the coastal area of the Haiyanghong village in Dandong,Liaoning Province,the experiment is intended to trace and measure the variation of thesoil shear strength at a set of water content.Through the calculation of the indicators of ground strength and stability as well as the cohesion c and internal friction angle φ of the ooze cohesive soil in the area targeted,this article intends to make furthertest and verification of the ooze cohesive soil＇s varying pattern under various water content circumstances.
