一、概述在平原软土地基上建设的农田水利工程,由于土质抗冲刷能力低,泄水闸下游冲刷是一种普遍存在的问题。对于已建成的水闸,通过泄洪闸的控制运用,保证工程安全,是当前许多工程急待解的问题。根据已建成的昌源河水闸在运用中存在的下游冲刷问题,对七孔闸门的控制运用作了初步研究,供管理单位参考。昌源河是汾河的一条主要支流。昌源河灌区泄洪闸修建在昌源河主河道上。距上游子洪
I. Overview In the plain soft soil foundation construction of farmland water conservancy projects, due to the low resistance to erosion of soil, downstream sluice scour is a common problem. For the completed sluice, the control and application of the flood sluice to ensure the safety of the project is a problem that many projects are currently undergoing. According to the existing Changyuanhe sluice in the use of the downstream scour problems, the control of the seven-hole sluice made a preliminary study for the management unit for reference. Changyuan River is a major tributary of Fenhe. Changyuan River irrigated flood irrigation gates built in Changyuan River main channel. Sub-upstream from the flood
