特克斯河山口引水枢纽工程截流试验研究

Study on Experiment of River Closure of Tekesi \;Water Diversion Project

通过对特克斯河山口引水枢纽工程三个截流方案的优化试验研究，得到部分护底方案是可行的，获得了截流过程龙口的水流特性，确定了不同龙口宽度时抛投料的化引直径和合理的抛投强度，为工程截流的实施堤供了科学依据。

By three cutoff schemes optimal experiment about Tekesi water diversion project, in this paper the flow characteristics of closuregap during the closure was analysed,the equivalent diameter of dumped riprap and its reasonable intensity in the different closuregap width was decided. It shows that partial river bottom protection is feasible, which provides scientific basis for implementation of closure work.\;
