Gate scheduling method for reducing waves of double-groove type water delivery aqueduct
The invention provides a gate scheduling method for reducing waves of a double-groove type water delivery aqueduct. The method comprises the following steps of: 1, calculating a gate opening height ewhen a double-hole gate uniformly controls leakage according to a flow planned to pass through by a double-groove type aqueduct check gate and a corresponding downstream water level and according to awater level commonly arranged in front of the gate; and step 2, calculating the relative opening height e/H of the gate according to the gate opening height e and the water depth H in front of the gate, if the relative opening height e/H of the gate is less than or equal to 0.65, performing uniform discharge control operation on the double-hole gate according to the calculated gate opening heighte, and if the calculated relative opening height e/H of the double-hole gate is more than 0.65, not controlling the water level in front of the gate; A one-hole gate is fully opened for discharge, aone-hole gate is partially opened for discharge control, and the relative opening height e/H of the one-hole gate for discharge control operation needs to meet the condition that e/H is larger than 0.65 and smaller than 0.75. The method is simple and practical, large waves generated in the operation process of the double-groove type water conveying aqueduct can be remarkably reduced, and the operation condition of the aqueduct is improved.
本发明提供一种消减双槽式输水渡槽波浪的闸门调度方法，包括步骤：步骤一、根据双槽式渡槽节制闸拟通过的流量及对应的下游水位，按闸门前常设水位计算双孔闸门均匀控泄时的闸门开启高度e；步骤二、根据闸门开启高度e和闸门前水深H计算闸门相对开启高度e/H，如闸门相对开启高度e/H≤0.65，则按计算的闸门开启高度e进行双孔闸门均匀控泄运行，如计算的双孔闸门相对开启高度e/H＞0.65，则不控制闸前常设水位，采用一孔闸门全开敞泄、一孔闸门局开控泄方式运行，其中控泄运行的一孔闸门相对开启高度须满足0.65＜e/H＜0.75。本发明简单实用，能够显著消减双槽式输水渡槽在运行中出现的大波浪，改善渡槽的运行条件。
