| 摘 要： | 采用二维有限元技术分析矩形抗滑桩桩间土土拱效应问题,得知在一定的桩间距下桩土效应较为明显,并通过案例对桩间距和桩问土粘聚力对桩土效应的影响作了分析,提出土拱效应的存在条件,土的性质对土拱效应的影响,得出工程实际中合理的桩间距.

| Abstract: | This paper conducts an effective analysis on the arching effect of soil between anti-slide piles,which are arranged in rectangular patterns,by two-dimensional finite element technique.This research indicated that the pile-soil effect seemed to be obvious when the piles were arranged at certain spacing.The effect of spacing between piles and cohesion of soil on the pile-soil effect was analyzed by case study.The occurring condition for arching effect was obtained;the effect of property of soil on arching eff... |
