Stability of Strip Footings Above Continuous Voids

这项研究的主要目的是研究位于连续空隙上方的条形基础的性状，并发展一种用于基础稳定性分析的分析方法。计划结合不同的空洞形状、大小和位置来研究不同的加载条件。这些实验将在不同类型的土壤上进行。如高岭石粘土、粉质粘土和砂质粘土。用有限元方法和塑性极限上限定理分析了地基的受力性能。在此基础上，建立了条形基础承载力的计算公式。PI是唯一有资格进行这项实验和理论研究相结合的研究的机构。研究成果对岩土工程设计中存在天然空洞的地基具有重要意义。建议设立一个奖项。

The primary objectives of the proposed research are to investigate the behavior of strip footings located above continuous voids and to develop an analytical method for foundation stability analysis. It is planned to study different loading conditions in combination with different void shapes, sizes and locations. These experiments will be conducted with different types of soils. Such as kaolinite clay, silty clay, and sandy clay. The behavior of the footings will also be analyzed by using a finite element method, and the upper bound limit theorem of plasticity. Based on these results, equations for computing bearing capacity of strip footing will be developed. The PI is uniquely qualified to conduct this research which is a combination of experimental and theoretical study. The outcome of the research will be of major importance to geotechnical engineering in design of foundation where the ground has natural cavities. An award is recommended.
