基于蛙跳优化算法的土石坝邓肯-张E-B模型参数反演

邓肯-张E-B模型常用来刻画土石坝本构关系,对其参数进行准确估计是实现土石坝应力应变分析的前提。本文针对工程中通过三轴试验确定其参数所存在的不足,着重阐释了群智能蛙跳优化算法在反演土石坝邓肯-张E-B模型参数中的应用,结合实测资料,通过正分析,证明了蛙跳优化算法在E-B模型参数反演中的合理性,以期为其他工程提供借鉴。

Earth and rockfill dam Duncan-Zhang E-B model parameter inversion based on leapfrog optimization algorithm

Duncan-Zhang E-B model is usually used for depicting the constitutive relation of earth and rockfill dam. Accurately estimating the parameters is the precondition for realizing earth and rockfill dam stress and strain analysis.In the paper,the application of swarm intelligence leapfrog optimization algorithm in inversion earth and rockfill dam Duncan-Zhang E-B model parameter is mainly described aiming at the defect of determining the parameter through triaxial test in the project.Survey data is combined.The rationality of leapfrog optimization algorithm in E-B model parameter inversion is proved through positive analysis,thereby providing reference for other projects.
