混凝土重力坝止水位置对闸墩应力的影响研究

Influences of Water-Seal Position on Pier Stress of Concrete Gravity Dam

结合工程实例,对比分析了混凝土重力坝止水位置优化前后闸墩前部及胸墙的应力变化。分析结果表明,高水头混凝土重力坝止水位置对闸墩应力会产生较大的影响。止水位置后移以后,闸墩及胸墙的应力明显改善。

The fore-and-aft changes the position of water-seal of concrete The analytical results show that the will cause a larger influences on the of stress with the optimization at the front of pier and the crest wall at gravity dam are compared in accordance with the engineering cases. position of water-seal of concrete gravity dam with high water head stress at pier. The stresses at pier and crest wall will improve obviously when the position of water-seal is moved back.
