威信县鳞凤乡分干渠工程设计

Sub-main Channel Engineering Design for Linfeng Countryside in Weixin County

渠道工程是水利工程的重要组成部分之一,无论蓄水、灌溉,利用水力发电,或排除洪涝积水,都需要通过渠道才能发挥效益。云南省威信县鳞凤乡黄水河水库的分干渠以灌溉为主,兼顾人畜饮水、防洪、发电等功能。以水力学原理和相关设计规范为依据,对鳞凤乡分干渠进行设计,通过指标计算,在经济理论上是合理的,工程设计灌溉面积800 hm2,可使水利化程度由8.8%提高到30.5%,使GDP每年增长10%。

A channel engineering is an important part of water conservancy engineering. No matter what water conservation, irrigation,generating electricity by using waterpower or removing flood water ,using channel system is necessary for getting normal function. The sub-main channel for Huangshuihe reservoir,which is located at Linfeng countryside of Weixin county in Yunnan Province ,is designed for irrigation,human and domestic animals drinking,controlling flood and generating electricity, etc. Based on the hydraulics theory and related design standards, the sub-main channel engineering design for Linfeng countryside is demonstrated, which is reasonable on economy through index calculation. The engineering design area for irrigation will reach 800 hmz. Water conservancy degree will be raised from 8. 8% to 30. 5% and the value of GDP will increase by 10%.
