摘要
通过水力学整体模型试验,分析龙口截流过程中水力学要素的分布规律,研究确定了澜沧江黄登水电站截流工程戗堤的布置、龙口位置的选择、截流水力学参数及进占过程中抛投方式的选择,同时研究了水流对1#导流洞进口全年围堰爆破后的冲渣情况及对导流洞分流能力的影响。结果表明,不论导流洞进口爆渣为何种形式,在Q=695 m3/s(11月中旬P=10%)至Q=1 380 m3/s流量下都无法将爆渣冲出导流洞,模型试验为工程施工及技术方案的编制实施提供了科学依据。
Through the hydraulic model test , the distribution law of the hydraulic elements of Longk-ou closure process , research on the Lancang River Huangdeng Hydropower Station closure dike lay-out , closure gap position , the vote cast River hydraulics parameters and enter the selection process.The Tests have also studied the slag flushing water diversion tunnel inlet condition of 1#year after cof-ferdam blasting and influence , the diversion tunnel diversion capacity.The results showed that the entrance of the diversion tunnel blast slag regardless of what form , in the Q=695 m^3/s （ November P=10%） to the Q=1 380 m^3/s flow will not burst out of the diversion tunnel of slag , and provide scientific basis for the model test for the preparation of project construction and technical engineering implementation.
