摘要
本文通过有限元与优化理论的结合,提出了一种新的简单的地下工程围岩压力计算的反算法。它以实测位移(或应力)为理论根据,利用优化方法将计算应力(或位移)向实测应力(或位移)逼近,从而反推算出作用在巷道支护上的围岩压力分布。应用了SAP5分析程序和Hooke—jeeves优化方法,对计算地下工程围岩压力分布进行了新的探讨,它将在地下工程设计及地压研究等方面起着重要的参考作用。
This paper applies the combination of the finite element with an optimal method, and a new easy calculation of the pressure of rock in the underground engineering is pressented. It is based on the translation actually measured uses the optimal method for calculating stresses to approach the stress actually method so that the law can be counter-calculated of the pressure distribution of around rock on the tunnel. It also applies both the advanced finite element analysis program-SAP5 Hooke-Jeeve's optimal method, presenting a new way for the calculation of the pressure distribution of the around rock in the underground engineeering. It will play a great part in the design of the underground engineering and the research of the underground pressure.
