| 摘 要： | 在水电站施工过程中,当遭遇超标准洪水时,围堰发生漫顶溃决,将对工程施工及下游城市安全产生巨大的影响.通过水工模型试验并结合数学模型,对景洪水电站二期围堰溃决对下游影响进行研究分析.试验结果表明:下游围堰渐溃,对下游地区影响较小,而上游围堰溃决对下游地区影响较大,其瞬溃的影响尤甚;同时,数值计算结果与物理模型实测数据吻合较好.

| Abstract: | During the dam construction,it is possible that a transnormal flood occurs,and then the cofferdam will be broken down,which will cause an enormous effect on the security of the construction and the cities along the lower course.On the basis of the hydraulic model test and numerical computation of the cofferdam-break,the effect of the cofferdam-break on the lower reach of Jinghong Hydroelectric Station is analyzed.And the result shows that:(1) the gradual breaking of the downstream cofferdam has a tiny effec... |
