对从三城垃圾填埋场收集的城市固体废物（MSW）进行了大规模三轴压缩和直剪试验，以评估城市固体废物的单调应力应变（或应力位移）响应。结果表明，根据样品废物成分和剪切模式的不同，排水剪切响应可能会有显着差异。使用三轴和直接剪切测试装置进行的不同剪切速率的分阶段测试表明，城市固体废弃物的响应受到剪切速率的显着影响。因此，城市固体废弃物的动态剪切强度可以显着高于其静态剪切强度。
Large scale triaxial compression and direct shear tests were performed on Municipal Solid Waste (MSW) collected from the Tri-Cities landfill to evaluate the monotonic stress-strain (or stressdisplacement) response of MSW. The results indicate that the drained shear response may differ significantly depending on the specimen waste composition and the mode of shearing. Staged tests with varying shearing rates performed using triaxial and direct shear testing devices indicated that the response of MSW is significantly affected by the rate of shearing. Thus, the dynamic shear strength of MSW can be significantly higher than its static shear strength.
