摘要 本文根据工程实践和试验资料,对河床式泄水建筑物在特定条件下出现的强压气囊、水跃打闸门、振荡水流等几个水力学问题,就其发生机理、危害程度、克服办法等进行了初步分析和探讨。 For Spill-structmeson river bed, strong pressure gas pocket, oscillating flow and jump striking the gate may occur under particular conditions. Based on eogineering prance and experiment data, these hydraulic hydraulic are preliminarily analysed and studied in thes paper for their mechanism, harm degree arid the method to solve the problems.
