基于Autobank的沥青混凝土心墙堆石坝应力-应变分析

摘要

Because current domestic and foreign large commercial software,such as ABAQUS,ANSYS,FLAC3D,do not provide Duncan-Chang model.The finite element calculation program Autobank,which designed for water conservancy and hydropower industry in China,is adopted to analyze the stress-strain of the rockfill dam with asphalt concrete core wall in Quxue Hydropower Station.The calculation results show that the stress and deformation of rockfill dam are consistent with actual construction and operation process of dam under two operation conditions.The comparison with displacement monitoring results also shows that the calculation program is efficient and accurate and can be widely applied to stress-strain analysis of rockfill dam.%针对目前主流的ABAQUS、ANSYS、FLAC3D等国内外大型仿真软件本身没有提供邓肯-张模型的不足,基于去学水电站沥青混凝土心墙堆石坝,采用针对我国水利水电行业要求而设计的有限元计算程序Aumbank对其进行了应力应变分析.计算结果表明:在两种工况下,堆石体应力变形结果符合大坝实际施工及运行过程变化规律.与位移监测结果对比分析可知,该计算程序高效、准确,可普遍应用于堆石坝工程的应力应变分析中.
