摘要
考虑桩、土之间相互作用的复杂性,编制有限元程序对滑坡防治工程预应力锚索抗滑桩结构的变形和受力进行分析,表明:①锚固段桩前滑床抗力主要集中在靠近滑动面部分;②在锚固段随锚索预应力和滑床刚度的大小改变可能出现反弯矩.
Considering the complexity of interaction between soil and pile, the paper wrote a FEA program to analyze the timbered coast and got the data of distortion and force distribution of pre-stressed anchor rope anti-slide pile, which indicated: ①in the anchoring sect, the bedding resistance is mainly centralized near slideway; ②in the anchoring sect, the pile's moment may change aspect with the variety of bedding stiffness.
