| 摘 要： | 根据垃圾土颗粒大、纤维质多等性质,自行研发了适合垃圾土的反复直剪仪,进行了垃圾土的反复剪切实验。通过对比3组不同深度垃圾土样的反复剪切实验数据,总结出垃圾土的反复剪切性质,得出反复剪切的破环强度、峰值强度和残余强度,并根据破环强度值得出垃圾土的c、φ参数。对比国外填埋场失稳反演得出的垃圾土强度,得出以剪切应变ε=10%作为垃圾土强度的取值。

| Abstract: | According to the characters of municipal solid waste (MSW),such as large particles and much fiber,experimental equipment for the repeated shear of MSW was designed and made by ourselves.Through the comparison of the repeated shear experimental data of three soil samples from different depths of a landfill,the shear properties of MSW,the damage strength,peak strength and residual strength of the repeated shear were obtained.The strength parameters(c,φ)of the soil were acquired.Comparing the results from domestic and foreign scholars,the stress strength(ε=10%)similiar to the value abtained from the landfill failure. |
