通过开展不同温度下土的三轴剪切试验,获得了不同围压、不同温度下饱和黏土的应力-应变特性曲线,分析了温度对饱和黏土强度特性的影响,讨论了三轴抗剪强度与温度、围压的关系。结果表明:不同温度和围压下试样的剪切曲线均呈现较为明显的温度硬化形态;随温度的升高,黏性土的c,φ值均有所减小,土的强度降低;软黏土抗剪强度的温度效应与试样所受的围压有一定的关系,围压越大其温度效应越明显。 By carrying out triaxial shear tests of soils at different temperatures, the stress-strain curves of saturated clays at different confining pressures and temperatures are obtained. The influence of temperature on the strength characteristics of saturated clays is analyzed. The effects of triaxial shear strength and Temperature, confining pressure relationship. The results show that the shear curves of the samples under different temperatures and confining pressures all show obvious temperature hardening forms. As the temperature increases, the c and φ values ​​of the clay decrease and the strength of the soil decreases. The temperature effect of clay shear strength and the confining pressure of the sample have a certain relationship, the greater the confining pressure, the more obvious the temperature effect.
