摘要:
针对渗透系数反演结果不唯一问题,以扬压力和渗流量2类渗流监测效应量为反演目标,建立了基于正交设计、有限元正分析和GA-BP相结合的渗透系数多目标反演分析模型。结合水口大坝2009—2018年渗流监测时间序列数据,开展了大坝坝体、坝基岩体渗透系数反演研究,并对反演结果进行了验证。研究结果表明:建立的渗透系数反演模型可较好地解决渗流单目标反演的缺陷,反演结果为绝对渗透系数,且反演结果真实可靠。
Abstract:
Aiming at the problem that the inversion results of permeability coefficient were not unique,two kinds of seepage monitoring effect quantities including the uplift pressure and the seepage quantity were used as the inversion objectives,and the multiobjective inversion analysis model of permeability coefficient based on the combined methods of orthogonal design,finite element positive analysis and GA-BP was established.Combined with the time series data of the seepage monitoring in the Shuikou dam from 2009 to 2018,the inversion research on the permeability coefficients of the dam and dam foundation rock mass was carried out,and the inversion results were verified.The results showed that the inversion model of permeability coefficient could solve the defect of seepage singleobjective inversion better.The inversion results were the absolute permeability coefficients,which were true and reliable.
