摘要:

针对市政系统和水利系统中设计暴雨重现期不一致的情况,提出基于年多个样法和年最大值法的次风险理念和年风险理念.指出市政系统重现期所表征的风险除特大值外还包括次大值等所引起的风险,而水利系统重现期所表征的风险仅为年最大值主宰的风险.以广州市暴雨资料为例,分析2种重现期的大小关系.研究表明,市政系统重现期小于或等于水利系统重现期的数量关系,2种重现期化异求同的关键在于统一风险理念和选样时采用年最大值法.

Abstract:

The concepts of time-risk and annual-risk were respectively presented based on the annual multi-samples method and the annual maximum sample method aiming  at the inconsistent of return periods about design rainstorm in the municipal and water conservancy systems. The risk of municipal system was caused by the annual biggest flood or the second flood or others, but the risk of water conservancy systems was  caused by the annual biggest flood. Taking the storm data in Guangzhou city as an example, the relationship between the two kinds return period was deeply analyzed. Results show that the return period of municipal system is not more than water conservancy system. The  key to change  the two return periods into accordance is unifying the two risk concepts and adopting the annual maximum sample method.
