KS水库沥青混凝土心墙坝二维有限元静力计算

Two-dimensional Finite Element Static Calculation of Asphalt Concrete Core Dam of KS Reservoir

沥青混凝土心墙坝作为发展最晚的一种大坝防渗型式,近几年在水利工程中的应用也逐渐增多,如何计算在不同时期及工况下坝体及心墙的应力状态成为了最为关键的研究内容之一。采用平面非线性有限元方法,对KS水库沥青混凝土心墙坝进行了二维非线性有限元数值模拟,并对坝体在施工和蓄水期间的应力、应变、位移分布、变形等进行了数值模拟和分析。结果表明,过渡料和心墙基本符合设计规范,不会产生水力劈裂。

As the latest type of dam seepage prevention, asphalt concrete core dam has been applied more and more in hydraulic engineering in recent years. How to calculate the stress state of dam body and core wall under different periods and conditions has become one of the most critical research contents. Two-dimensional nonlinear finite element numerical simulation of asphalt concrete core dam of KS reservoir is carried out with plane non-linear finite element method. Stress, strain, displacement distribution and deformation of dam body during construction and impounding are simulated and analyzed. The results show that the transition material and core wall basically conform to the design specifications and do not generate hydraulic splitting.
