摘要
水利工程存在多种导流方式,其中土石坝工程因为其自身特点多采用一次拦断河床围堰导流方式,常常设置导流明渠作为施工期泄水建筑物。为节省工期、投资、平面空间可考虑导流明渠与溢洪道结合布置,但需考虑导流明渠与溢洪道在高程、规模方面的差异。设置双溢洪道,其中一个溢洪道与导流明渠结合布置的方案可减小这两个差异,实现两者结合布置。
There are many diversion ways in the Hydraulic engineering,among which the diversion channel is often used as the drainage structure during the construction period because of the characteristics of the earth-rock dam project.In order to save time,investment and plane space,the combined arrangement of diversion channel and spillway should be considered,but the difference of elevation and scale between diversion channel and spillway should be considered.The scheme of setting double spillways,one of which is combined with diversion channel can reduce these two differences and realize combined layout.
