关于直立墙前的立波压力,自1928年法国工程师森弗罗在椭园余摆线波理论的基础上求得数学解以来至今已有很多的理论计算方法。但是这些理论计算的结果有的互相之间相差较大,目前由于原型观测和模型试验技术的不断开展,对进一步校核这些理论的正确性和使用条件,并探讨新的计算方法更加引起了各国学者注意,特别是对直立墙前的浅水立波压力的试验研究。它将直接对直立式水工建筑物的设计产生较大的影响。因此本文选用了1979年在标定波浪水槽性能的试验中测得直墙前立波压强度,以及垂直分布情况的部分资料进行了整理分析,与几种理论计算方法和我国规范方法的计算值进行了比较探讨,其结果如下。
As for the standing wave pressure in front of an upright wall, many theoretical calculations have been made since the French engineer Senflor obtained the mathematical solution based on the elliptic trochoidal wave theory in 1928. However, the results of these theoretical calculations are quite different from each other. At present, due to the continuous development of prototype observation and model test technologies, the correctness and conditions for further examination of these theories and the exploration of new calculation methods have drawn more attention from countries Scholars have noticed, in particular, the experimental study of the pressure of shallow water in front of an upright wall. It will have a direct impact on the design of vertical hydraulic structures. Therefore, in this paper, some data of the vertical wall pressure and vertical distribution measured in the test of the performance of a wave tank in 1979 were selected and analyzed. Compared with several theoretical calculation methods and the calculated values of our country’s standard method Comparative study, the results are as follows.
