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.

拟议研究的主要目标是调查 位于连续空隙上方的条形基础的行为， 地基稳定性分析的解析方法。 计划 结合不同的空隙率，研究不同的荷载条件 形状大小和位置 这些实验将与 不同类型的土壤。 如高岭石粘土、粉质粘土和桑迪 克莱 基脚的行为也将通过使用 有限元法和塑性上限定理。 在此基础上，提出了计算钢筋混凝土梁承载力的公式 将开发条形基础。 PI是唯一有资格进行这项研究的人， 实验与理论研究相结合。 的结果 研究将是非常重要的岩土工程， 地面有天然空腔的基础设计。 一个奖项是 推荐
