深基坑开挖中预应力锚杆或预应力支撑支护结构的计算分析

The Analysis of the Retaining Structure with Prestressed Anchor or Prestressed Brace in Deep Excavation

对深基坑开挖中的预应力锚杆或预应力支撑的支护结构的受力计算提出了相应的计算方法,并通过工程实例的计算分析,说明预应力在减少支护结构的位移、改善受力状态中的作用.

On excavation of deep foundation pit, the mechanical calculation method is developed for the supporting structures with prestressed anchor rod or brace. The analysis example of project illustrate that the prestress can decrease the displacement and improve the state of mechanical in supporting structures.
