摘要
在分析了基坑开挖过程中预应力损失的规律情况下,对基坑开挖过程进行数值模拟,分析了预应力补张拉对基坑水平位移变形的影响。实践证明,预应力补张拉能够有效抑制土体的水平变形发展。
In the anchor prestressed construction process, pre-stressed anchor has the loss of deposit, and in the analysis of the process of excavation under the laws of prestress loss, we simulate the numerical excavation process, and analyse the prestressed tension filling the deformation of the foundation pit irnpact. It has proved that added tension prestressed soil can effectively inhibit the development of horizontal deformation.
