基于差异进化算法的隧道渗流反分析与工程应用
Intelligent back analysis of Tunnel seepage based on differential evolution algorith m and its engineering application
摘要
Abstract
In view of the change of seepage field caused by tunnel excavation,the surrounding rock was taken as porous continuous medium to obtain seepage parameters.Firstly,a seepage finite element calculation program (SEEP)was independently developed based on the variational principle using C++language,and the accura-cy of the program was verified.Secondly,a robust global optimization algorithm-differential evolution (DE)al-gorithm was introduced to combine with SEEP,and the seepage back analysis program (SBAP)was developed. Finally,the SBAP was applied to the real-world tunnel construction project from Jinzhou to Pulandian.Meas-urements of pore water pressure and water inflow were adopted to back analyze the horizontal and vertical permea-bility coefficients of the surrounding rock.The calculated results agree well with observed values,thus demon-strating that the DE algorithm can be applied successfully to the back analysis of seepage.This method provides a reference for the determination of seepage parameters and water inflow for tunnels with similar underground en-gineering conditions.关键词
