摘要
针对预应力锚杆柔性支护工程中的锚杆长度、间距、支护倾角以及面层厚度的选择问题 ,运用非线性有限元进行了结构的参数变化研究 ,研究了锚杆长度、间距、倾角和厚度的变化对基坑的变形和锚杆内力的影响 ,进一步了解锚杆支护的作用机理 。
A nonlinear finite element analysis is presented to study the effects of the structural parameter of the prestressed anchor flexible retaining.Attentions are paid to the problems,such as different anchor length,anchor space,shoring obliquity and surface thickness.The effects of these factors on the deflection of excavation and internal force of anchor are considered.The mechanics of the anchor support is indicated more deeply.At the same time the results of the paper provide the references to designing for actual engineering.
