基于离散元的不同截面抗滑桩土拱效应分析
Analysis of soil-arching effect of anti-sliding piles with different cross-sections based on DEM
摘要
Abstract
We choose three typical cross-sections of anti-sliding piles (square, rectangle, circular) to study their soil-arching forming and developing mechanisms and the related influential factors from microscopic perspective based on DEM.The results show that soil-arching effect forms behind the three types of anti-sliding piles, the soil arch of square pile and rectangle pile is semi-circle shape, and the circular pile's soil arch is saddle-shaped.The ultimate bearing capacity of rectangle pile is the largest, square pile is the second, and the circular pile is the smallest.Different influential factors have different influences and degrees on the anti-slide piles, while the same factor affects anti-slide piles of different sections in the same law but with different degrees.关键词
