Abstract: As the existence of concrete cracks in constructed dams, there would be latent risk for these concrete hydraulic structures. In the paper, Dongzhou concrete pier was researched, mechanics method was used to analysis the pier safety in the three dimensional nonlinear finite element method. From the calculating result, some conclusions were gained about pier safety and the crack development in the future was forecasted.

摘要： 已建水库大坝中, 由于混凝土裂缝的存在, 对水工混凝土结构的安全性造成了潜在的风险。本文以东周水库混凝土闸墩为研究对象, 用力学分析的方法对裂缝存在下的闸墩进行了三维非线性有限元分析, 根据计算结果对东周水库的闸墩的安全性进行了评价, 并预测了裂缝未来的发展趋势。
