本文介绍了旧金山湾区三城垃圾填埋场城市固体废物动态特性评价的实验室试验结果。采用大型循环三轴试验测量了小应变剪切模量、Gmax、归一化剪切模量折减曲线和材料阻尼比曲线。测试结果被认为是深度达20米的代表性结果，用于研究废料的动态特性与试样组成、约束时间、材料单位重量和加载频率的关系。
Results of laboratory tests are presented for the evaluation of dynamic properties of Municipal Solid-Waste (MSW) from the Tri-Cities landfill in the San Francisco Bay Area. Values of small-strain shear modulus, Gmax, and the normalized shear modulus reduction and material damping ratio curves are measured using large-scale cyclic triaxial tests. The test results, which are considered representative for depths up to 20 m, are used for investigating the dependence of the waste material’s dynamic properties on specimen composition, duration of confinement, unit weight of material, and loading frequency.
