玉马灌区水资源供需平衡及隧洞加固方案分析

Analysis of Water Resource Supply and Demand Balance and Tunnel Reinforcement Scheme in Yuma Irrigation District

根据灌区供需水平衡分析,在设计保证率P=50%的年总来水量总体上可满足项目用水需求;结合工程实际情况,对西一分干渠、东干渠进行清淤加固,通过复核分析加固改造后,不影响沿线取水口正常取水,同时增加了安全输水能力,降低了水渗漏。可为类似灌区工程改造加固提供参考。

According to the analysis of water supply and demand balance in irrigation district,the total annual water supply with the design guarantee rate of 50%can meet the water demand of the project.Through rechecking and analyzing,the normal intake of water along the line is not affected.The safe water delivery capacity is increased.The water leakage is reduced.It can provide reference for similar irrigation district engineering reconstruction and reinforcement.
