用并层非均匀单元法分析碾压混凝土拱坝温度应力

Thermal stress analyses for roller compacted concrete dam by layer-merged and heterogeneous element method

摘要: 在并层算法和非均质单元法的基础上，提出了采用均质模型和等效变形模型的并层非均匀单元法。经验证，并层非均匀单元法可行、实用，且计算精度和效率较高。

Abstract: A layer merged and heterogeneous element method,using homogeneous model and equivalent deformation model,is developed based on the layer merged algorithm and heterogeneous element method.Calibration shows that the layer merged and heterogeneous element method is feasible and practical with high calculation accuracy and efficiency.
