弹性地基梁法在基坑支护中的应用

An Application of the Beam on Elastic Foundation Method in the Deep Excavation

以成都某建筑场地深基坑设计为例,介绍弹性地基梁法设计基坑支护,包括内力计算,使用Bishop法判断基坑的稳定性,并使用不同方法得出地表沉降量,分析了弹性地基梁计算在基坑支护设计中的优缺点。

This paper presents a case study of a deep excavation design in a building in Chengdu. The application of the beam on elastic foundation method in the deep excavation design as well as the internal force estimation is introduced. The stability of the excavation is evaluated by using Bishop Method. Various methods are used to estimate the excavation induced ground settlement. Both advantages and disadvantage aspects of the beam on elastic foundation method in the deep excavation design are also discussed.
