INTERACTION ANALYSIS ON WALE AND RETAINING PILES IN DEEP FOUNDATION PIT
深基坑圈梁与支护桩的相互作用分析

A semi-spatial model is presented to analyze the behavior of retaining piles in deep excavation. Based on free support assumption at the bottom of the piles,the analytical formula is derived to calculate the bending moments and deformations of the piles. The formula can account for the top-beam and strut-wale effects. Finally, the spatial effect of this kind of structure and influence of the wale are shown through a case study.
