【摘要】 本文根据我国某河流中上游流域特征，通过对该流域水文等资料进行分析与研究，得出在该河流建设水闸防洪的结论，本文在水闸的结构布置设计中，以结构布置满足防洪标准及结构安全要求为前提，以经济角度对水闸的各组成部分进行方案研究与优选，选出经济合理的结构型式。本文通过对在该河流上建设水闸进行了国民经济评价。本文在设计规范的基础上针对水闸的结构设计，采用有限元对深孔闸的闸室进行了分析计算，根据空间板的分析理论，在原薄板问题的受力计算基础上考虑了闸内力的作用。此方法简便易行，精度较好，是分析深水闸薄板结构的有效方法。更多还原

【Abstract】 Based on characteristics of middle and upriver drainage areas of a river in our country, this paper analyzes and studies some hydrological information and draws a conclusion of floodgates, flood prevention standards and structure safety requirement are adopted as premises and compositive parts of floodgates are studied from an economical point of view. An economical and reasonable structure type was selected as an optimization. This paper also gives a process of national economic evaluation on building floodgates in this river. Based on structural design criterion of floodgates, a finite clement method is adopted to analyze and calculate deep-hole gate chamber. And based on space plank analysis theory, area stress is considered in the stress calculation of original laminose problems. The method is simple, convenient and manageable and reaches better precision. In analyzing laminose structure of deep-hole gate, the method is effective.更多还原
