摘    要:用GDS非饱和三轴试验系统对宁明膨胀土进行了饱和状态下的固结排水试验以及控制基质吸力的非饱和三轴排水试验,分析得到了不同基质吸力下非饱和土的总粘聚力及吸附强度与吸力之间的关系.并对试验结果进行了数值拟和,由此获得了宁明膨胀土非饱和抗剪强度表达式.将参考文献中同类试验结果代入,同样满足此关系.

关 键 词:非饱和膨胀土  三轴试验  基质吸力  抗剪强度  表达式

Abstract:A consolidated undrained triaxial compression test and a suction-controlled drained triaxial compression test on Ningming expansive soil are conduced using GDS unsaturated triaxial testing system.Total cohesive strengths under different states of matric suction,as well as a relation between suction strength and matric suction,are obtained from the tests.A shear strength formula of Ningming unsaturated expansive soil is put forward as result of regressing the testing result.Some results from unsaturated expansive soilsp triaxial tests in references are also satisfied with the formula.
Keywords:unsaturated expansive soil  triaxial test  matric suction  shear strength  formula
