作者:胡跃斌 刘炜 王临清 张永平
摘要: 为解决常规断面间距计算中存在的物理概念不明确、计算方法不统一、计算成果精度较低等问题,提出了容积等效断面间距的概念和计算公式,阐述了容积等效断面间距的高程分级标准、计算流程及特殊问题的处理方法。利用2010 年小浪底水库实测数据,对该水库不同高程的容积等效断面间距进行了率定、计算。经过2011 年和2012 年4 个测次实测资料的检验,表明库容计算结果的精度明显提高,满足有关规范的要求。

Abstract: In order to solve the problems in conventional section spacing calculation such as unclear physical concepts,non-uniformed calculation method and lower precision of calculation results,this study introduced the concept and formula of volume equivalent cross-section spacing as well as dealing ways for special problems.Based on the measured data of Xiaolangdi reservoir in 2010,the volume equivalent cross-section spacing of different elevation were calibrated and calculated,and then checked by observed data in 2011 and 2012,it proved that the result precision was obviously improved and met the standard requirement.
