摘要

利用大型通用有限元分析软件ABAUQS的用户开发平台，实现了Duncan-Chang 模型的接口开发，完成了某沥青混凝土堆石坝的填筑与蓄水过程二维非线性有限元仿真模拟，得到了坝体和沥青混凝土心墙的应力与变形等结果，其成果对工程坝体断面优化分区、沥青混凝土心墙防渗设计可提供参考依据；同时表明：充分利用ABAQUS已经具备的非线性分析功能，二次开发是完成土石坝非线性应力应变分析的有效解决方案。

Abstract

Based on the use-developed platform of the general-purpose FEM system ABAQUS

Duncan-Chang constitutive model was numerically implemented. Stress and movement analysis for an asphalt concrete core dam including the phases of filling and impounding were conducted by 2-D nonlinear FEM. The magnitudes of stresses and displacements of the dam and asphalt concrete core were obtained. All results are reasonable and capable of providing important reference to the optimization of cross-section zones and design of seepage of asphalt concrete core for the project. Moreover

by fully utilizing the nonlinear analysis capacities provided by ABAQUS

further development is a shortcut and an effective solution to accomplish stress and strain analysis for earth-rock dam.
