摘要
邓肯E-B模型广泛应用于土石坝水利水电工程平面应变状态下的应力应变分析中,但对真实三维应力状态下的模拟仍有不足之处。针对前人提出的考虑中主应力影响的改进E-B模型,基于FLAC3D提供的二次开发平台对改进的邓肯-张模型进行程序实现,验证结果与试验结果吻合较好,从而可以验证所开发模型的正确性,并且可为土石坝水利水电工程坝料试验研究提供借鉴和参考。
Duncan E-B model is widely used in the stress-strain analysis of earth-rock dam water conservancy and hydropower projects under plane strain conditions,but it still has shortcomings in simulating real threedimensional stress states.Aiming at the improved E-B model proposed by previous researchers,which considers the influence of intermediate principal stress,this study implements the improved Duncan-Chang model through programming based on the secondary development platform provided by FLAC3D.The verification results are in good agreement with the test results,which confirms the correctness of the developed model and can provide reference for the test research on dam materials in earth-rock dam water conservancy and hydropower projects.
