黄松峪水库溢洪道加固设计与思考

Design and consideration of spillway reinforcement for Huangsongyu Reservoir

北京大部分水库建成于20世纪50—70年代,受当时条件限制,水库大多"先天不足",随着时代进步及规范的不断更新,在水库的除险加固中,弧门支座复核计算不满足现行规范是非常常见的问题。对此通常采取的加固措施有拆除重建、补强加固等,但降低门前水压力荷载这种非工程措施其实是更为简便的处理方式,本文详细介绍了黄松峪水库溢洪道的加固设计,望能对其他工程起到一定的参考作用。

following with the progress of the era and the continuous renewals of the relevant specifications,it is a common problem of that the re-check calculation made on the radial gate support cannot meet the requirement from the current specification during the risk-elimination and reinforcement of reservoir. Therefore,the reinforcement measures usually adopted are demolition and reconstruction,strengthening and reinforcement,etc.,however,the non-engineering measure of lowering the water pressure in front of gate is actually a more simple and convenient treatment method. The reinforcement design of the spillway for Huangsongyu Reservoir is described in detail herein,so as to play a referential role for the other similar projects.
