设上游底缝对高拱坝应力状态的影响

Effect of Upstream Bottom-joint on Stress Conditions of High Arch Dam

应用三维有限元方法对小湾高拱坝设上游底缝的影响规律进行了初探,分析了无缝和有缝以及干缝与湿缝对拱坝应力和变位的影响规律。结果表明:设上游底缝是改善拱坝应力状态的一个有效的工程措施。

The FEM is adopted to study the effect of upstream bottom-joint on stress conditions of Xiaowan high arch dam. The result of analysis demonstrates that the setting of upstream bottom-joint is a suitable measure for improving the stress condition of arch dam.
