【摘要】 采用自编三维非线性有限元模型对双河拱坝的坝体和地基进行了不同工况下的应力敏感性分析。结果表明,温降是坝体裂缝产生和扩展的主要原因,坝基材料的极度不均匀是坝体裂缝发生的内因。更多还原

【Abstract】 A self-programming three dimensional nonlinear finite element code is employed to analyze the stress sensitive on the dam and the foundation under different types of loading case.The results are obtained as followed: the temperature drop is the main external cause of crack formation,while the extremity of asymmetry of the foundational material is the important internal reason resulting in crack producing.更多还原
