| 摘 要： | 竖向预应力锚索抗滑桩是一种锚索从桩顶竖向穿过抗滑桩,直接嵌入基岩以下的新型抗滑桩.本文以某滑坡治理工程为例,采用数值模拟方法,研究竖向预应力锚索抗滑桩的内力,从桩长、锚固力、偏心距几个方面对竖向预应力锚索抗滑桩的桩身结构进行优化研究.模拟研究结果表明,其他条件不变时,竖向预应力锚索抗滑桩随着桩长的减小,桩身弯矩最大值变...

| Abstract: | The anti-slide pile with vertical pre-stressed anchor is a type of pile that is passed through by vertical anchors from top to the bedrock.This paper is based on an engineering project.Numerical simulation method is used to study optimal design of the anti-slide pile with vertical pre-stressed anchor.Several aspects are considered and include the pile length,the anchoring force and eccentricity.The numerical results show that when other conditions are the same,the maximums of bending moment of the pile body... |
