溪洛渡水电站拱坝设计

The design of Xiluodu arch dam

通过对溪洛渡混凝土双曲拱坝坝体应力分析、基础变模值的改变和坝身开孔等对坝体应力影响分析以及就坝基玄武岩发育的层间层内错动带进行坝肩大块体、小块体和阶梯状滑块的稳定分析，并应用三维非线性整体稳定分析计算，综合评价了溪洛渡拱坝设计的合理性。

On the basis of the stress analysis of the dam body,the change of foundation modulus value and the effect of dam hole on the stress,and the stability analysis of large blocks,small blocks and bench slide blocks in the inter and in layer disturbed belt in the basalt developed foundation in the Xiluodu concrete double curvature arch dam,the reasonability of the design of Xiluodu arch dam had been comprehensively evaluated by the three dimensional non linear integrity stability analysis method.
