从排洪抢险工程设计谈对重现期的一些看法

简要介绍了3项排洪抢险工程的设计概况和主要参数,分别采用重庆市暴雨强度公式和公路科学研究所的防洪经验公式对不同重现期的雨水量进行了计算对比,初步探讨了暴雨强度和重现期的关系并建议适当提高"排水规范及规划规范"中的重现期标准。

Speculations of Return Period Viewed from Perspective of Emergency Flood Drainage Engineering Designs

This article briefly introduced three general situations and main parameters in Emergency Flood Drainage Engineering Designs, adopted two formulae： rainstorm intensity formula of Chongqing and the Highway Science Institute＇s flood control experience formula, calculated the rainwater quantities at the different return periods. Then discussed the relationship between rainwater quantities and return periods. And finally, the writer suggested that the standard of return period in drainage and plan code should be increased appropriately.
