摘要
针对危岩体力学参数反演这一工程问题,采用果蝇算法调用有限元计算程序的方式进行反演计算。在计算过程中,针对果蝇算法运用到实际工程存在的一些问题进行了种群搜索区间限定和初始种群位置随机生成的改进,并将改进后的果蝇算法运用到索风营水电站Dr2危岩体力学参数反演计算中,可为类似工程的反演计算提供参考。
Aiming at the engineering problem of the inversed calculation on the mechanical parameters of dangerous rock mass, an inversed calcualtion is made by FOA ( Fruit Fly Optimization Algorithm) coupled with FEM. During the calculation, both the swarm search interval limitation and the improvement on the random generation of the initial location of swarm are carried out for some problems from the application of FOA to the project, moreover, the improved FOA is applied to the inversed calculation of the mechanical parameters of the Dr2 dangerous rock mass at Suofengying Hydropower Station, which can provide a certain refer- ence for the inversed calculation of the similar project.
