金州隧道等效围岩参数反演研究

选用了以大型有限元分析法用软件ANSYS为开发平台，利用APDL语言编写具有全局优化能力的遗传算法，直接利用全州隧道变形量测数据反演围岩等效参数，对围岩类别相同的断面围岩变形值进行了预测，计算值与实测值吻合较好，证明本文计算方法合理，结果可靠。

Equivalent Wall Rock Parameter Inversion Research on Jinzhou Tunnel

In this paper,ANSYS is chozen as the developing platform which is a large - scale business software using finite unit analysis method. The APDL language is applied to compose the genetic calculation method which is capable of integral optimization to use directly Jinzhou Tunnel deflection determined to invert wall rock equivalent parameter and the wall rock deflections of cross section which belong to the same kind is predicted. The real values is it well with the calculation. Thus the calculation method in this paper is reasonable and the results are reliable.
