摘　　要：为研究淤泥质黏土在冻结情况下的力学性能,本文取用上海地区第(4)土层淤泥质黏土重塑后进行单轴抗压强度试验,得到其在不同冻结温度情况下的单轴抗压强度以及弹性模量。研究表明,冻结的淤泥质黏土在受压后主要破坏的是冻土表面,且冻土的单轴抗压强度与弹性模量都与冻结温度呈现很好的线性相关性,随负温的增大而增大。In order to study the mechanical properties of mucky clay under freezing conditions,uniaxial compressive strength tests were carried out on remolded mucky clay from the 4th soil layer in Shanghai,and the uniaxial compressive strength and elastic modulus under different freezing temperatures were obtained.The results show that the frozen mucky clay mainly destroys the surface of frozen soil after compression and the uniaxial compressive strength and elastic modulus of frozen soil have a good linear correlation with freezing temperature,increasing with the increase of minus temperature.
