(一)目前计算稳定断面尺寸主要河相关系式 如何比较正确地预估发展到稳定程度时的断面尺寸,在河道整治裁弯取直设计中,具有十分重要的实际意义的。因为在进行引河护岸工程的设计时,需要事先知道引河发展到稳定程度时断面尺寸,好进行护理,以限制引河继续发展,防止弯道重复出现未裁弯前情况,卽由弯道过急造成洩洪不畅,增加船只的航程,不利于防洪与航运的现象。 目前对引河发展到稳定时的断面尺寸(卽稳定河宽和稳定水深)的确定,多采用苏联阿尔
(1) How to calculate the cross-section size of the main river facies with stable section size when estimating the degree of stability to a certain extent is of great practical significance in the straightening design of river courses. Because in the river diversion project design, you need to know in advance the river reaches a stable degree of cross-sectional size, good care, to limit the river to continue the development, to prevent the recurrence of the corner has not been cut before the situation, 卽 caused by the curve too fast Poor flood discharge, increase the voyage of the vessel is not conducive to flood control and shipping. At present, when the river reaches a stable development, the section size (卽 stable river width and stable water depth) is determined by using the Soviet Union Al
