基于力传递模型的框架预应力锚杆支护结构计算

Computation of Frame Supporting Structure With Pre-stressed Anchor Bars Based on Force Transfer

采用古典铁摩辛柯理论对挡土板受力进行了详细推导,发现挡土板所受弯矩较大,弯矩通过与四周框架的固定传递到框架内部引起框架弯矩值的增大,因此提出一种基于力传递的计算模型,可以更为准确地对框架预应力锚杆支护结构的受力进行计算。利用C++ BUILDER,结合实例开发出相应的计算软件,结果表明,提出的设计理论是合理的。

Through the computation of bulkhead with classical theory of Timoshenko, it was found that the moment on bulkhead was large, and the moment was transferred to the beams. This article deduced a model with force transfer, it could better worked on the force computation of the structure. With C＋ ＋ BUILDER program, linking with real instance, a computaring software was developed. As the result showed, the theory of this paper was reasonable.
