摘要
本文提出了对岩体和岩性诸参数,包括其抗剪强度指标c、φ值进行弹塑性反演分析的一种全局优化方法,实践上得出了非线性逆问题的唯一解,将文中所建议的方法用于某电站试验洞的上项反演计算,其结果与实测值吻合良好。
In this paper, an overall optimization method for using elastoplastic analysis to inverse the parameters of rockmass and rock behaviours, including the vahues of с and ф, has been proposed and a practically unique solution for the inversion of nonlinerar problems has been obtained. When applied to the above-mentioned inversion for a test adit in a hydropower station, the method proposed in the paper has given results in good agreement with actual measurements.
