双排桩支护结构受力分析与设计计算的探讨

Stress Analysis and Design Calculation of Retaining Structure with Double-row Piles

文章对深基坑工程中的双排桩支护结构的受力与变形问题进行了研究。分析了桩间土对前后排桩所受土压力的影响,对矩形和之字形排列的双排桩的前后排桩所受土压力的的取值方法进行了分析讨论。利用结构力学位移法和弹性地基梁理论,推导出一种计算精度有较新改进的计算方法,为双排桩的设计计算提供了新的思路。

This paper makes analysis on the stress and deformation of retaining structure with double-row piles in deep foundation pit engineering.Specifically,the influence of soil between piles on the soil stress for pre-and post row piles is analyzed,and the value obtaining method of the soil stress for pre-and post row piles in rectangular and zigzag permutation is discussed.Finally,based on structural mechanics displacement method and elastic foundation beam theory,a new method which is improved in calculation ac...
