The Design Of Floodgates And The Finite Element Method In Gate Chamber Staucture

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.
