摘要
采用特有的裂缝单元模拟裂缝和特殊的杆单元模拟混凝土中的骑缝筋,对某枢纽工程总干闸胸墙裂缝危害性及处理措施进行了数值仿真分析。分析结果显示,此分析模型能较好模拟裂缝在外荷载下的变形及混凝土中钢筋的受力状态,对混凝土裂缝处理与加固设计提出了一条量化分析方法。
A numerical analysis for the cracks in the parapet in a water gate in a water conservancy project is carried out with the unique crack elements simulating the cracks and the special bolts crossing crack element imitating the reinforcement bars across the cracks. Results of the numerical analysis show that the deformation of the cracks under the external loads can be unstable if the cracks are not treated. The treatment parameters of grouting are also given by the simulation analysis.
