| 摘 要： | 通过3种应力路径的三轴试验,即同时控制吸力和净围压的12个三轴排水剪切试验、控制净平均应力的3个三轴收缩试验和控制吸力的3个各向同性压缩试验.对非饱和含黏砂土的强度、变形、屈服和水量变化特性进行了研究,得出如下结论:相同干密度,相同净围压作用下,吸力越大试样的剪切强度越大,剪胀性越强,应力应变曲线逐渐由应变硬化型向应变...

| Abstract: | Three types of stress path tests were conducted,that is,12 triaxial drained shear tests with controlled suction and net mean cell pressure,3 traxial shrinkage tests with controlled net mean stress and 3 isotropic compression tests with controlled suction.A series of studies were carried out on strength,deformation,yield and moisture change of unsaturated soils clayey sand.Some conclusions were drawn.The more suction,the bigger is shearing strength and dilatancy of soil sample,under the same density and net ... |
