摘要

采用三维非线性有限元数值分析方法对坐落于深覆盖层上的黄金坪沥青混凝土心墙坝进行应力变形计算,结果表明:在竣工期和满蓄期大坝的应力与变形都在规范允许范围内;位移分布规律基本合理;心墙不会发生水力劈裂,没有发生剪切破坏;沥青混凝土心墙与河床中央混凝土廊道和混凝土基座之间的错动变形较小;大坝结构设计是合理的。
By means of 3-D non-linear finite element methods,the stresses and deformations of Huangjinping Rockfill Dam with asphalt concrete core constructed on deep overburden were calculated and analyzed.Some conclusions are drawn as follows: the stresses and deformations of Huangjinping Rockfill Dam during the completion and impoundment periods are within the allowable range of the Chinese codes.The distribution rules of the displacement are reasonable.Hydraulic fracture and shear failure will not occur in the core wall.The deformation between the asphalt concrete core wall and the bed of concrete is small.The structural design of Huangjinping Rockfill Dam is rational.
