| 摘 要： | 目前,水泥土在工程当中已得到广泛运用.为了深入了解其力学性质,在大量三轴试验的基础上,对水泥土的破坏模式、应变软化相关特性进行了研究.试验结果表明:水泥土的破坏模式随水泥掺量的不同而发生变化;峰值强度、残余强度随水泥掺量及围压的增大而增大;临界应变(峰值强度对应的应变)则随围压增大而增大,随水泥掺量的增大而减小.

| Abstract: | Cement-stabilized soil has been widely used in civil engineering.In order to deeply understand the mechanical properties of the soil,the failure mode and strain softening properties are studied based on a large number of triaxial tests.The testing results show that the failure modes of the soil change with cement content,the peak strength and residual strength increase with the increasing of cement content and confining pressure,and critical strain(the corresponding strain to peak strength) increases with t... |
