本文讨论了一系列实验室测试，其中研究了城市垃圾的机械性能。这种材料除了具有高抗剪强度外，还特别强调缓解长期沉降。这是因为封闭式垃圾填埋场的实际使用取决于沉降风险。事实证明，预加载对于实现这一目标是有效的。此外，对建筑基础的性能进行了模型试验和数值计算，结果表明桩筏基础结合预压是一种很好的措施。
This paper addresses a series of laboratory tests in which the mechanical properties of municipal waste are investigated. In addition to the high shear strength of this material, a special emphasis is placed on the mitigation of long-term subsidence. This is because the practical usage of a closed landfill depends on the risk due to subsidence. It is shown that preloading is effective to achieve this goal. Moreover, model tests as well as numerical calculations were conducted on the behavior of a building foundation, which revealed that a piled-raft foundation combined with preloading is a good measure.
