摘要
本文用长江口航道淤泥进行室内波浪试验研究,得到波高在泥床上传播时沿程按指数函数衰减:H_l/H=exp[-K(l/L)~n]。函数的幂数n和系数K都是相对泥床厚度(D_s/D)、泥床含沙体积比(S_v)的函数,系数k还与波坦(L/D)和相对水深(D/H)有关。本文还探讨了波浪衰减与泥床波动、水体含沙浓度分布的关系,获得了波浪对泥床作用所产生泥沙运动的一些规律和特点。
This paper, based on tests in a wave flume by using silt from the navigation channel at the mouth of the Yangtze River,shows that the wave height on the siltbed decays exponentially along the distance of propagationwhere n is also an exponential function of the relative silt bed depth (Ds/D) and the volume ratio of silt content in the bed (Sv) , coefficient K is not only a funcition of (Ds/D) and (Sv) , but also' depends on reciprocal wave steepness(L/H) and the relative water depth (D/H).
