APPLICATION AND ANALYSIS OF SPARSE PILE SUPPORT FOR DEEP FOUNDATION
深基坑疏桩支护应用分析

The soil arch theory is applied to the foundation support. The Huachengdadao metro station foundation is taken as the relevant example in this paper to explain the application. Based on the analysis of the geological conditions, the soil arch theory is adopted in the optimal design of the foundation,and the Lizheng deep foundation software is used to calculate the foundation displacement and stability. The results prove that the sparse pile support for deep foundation is stable and economical,and the support pattern is worth developing.
