摘要
根据所导出三角形和复式三角形排导槽的最佳水力断面,三角形水力最佳断面β=1+m2-1,对梯形、矩形、三角形排导槽优化断面进行了比较,研究结果对规划设计有很强适用性。
The optimal hydraulic conditions of triangle cross_section and compound triangle cross_section were presented. The results show that the optimal hydraulic condition of debris flow drainage canal is that the ratio β of width b to depth h is 2 for triangle cross_section and β=1+m 2-1 for compound triangle cross_section. The hydraulic condition of different types (trapezoid, rectangluar, triangle and compound triangle) of debris flow drainage canal have been discussed. The conclusion of this study is of reference value for the disaster control and prevention.
