长洲三、四线船闸中间闸室墙结构有限元分析

Finite Element Analysis of Wall Structure of Middle Lock Chamber of Changzhou Third-Line and Fourth-Line Shiplock

长洲水利枢纽三线四线船闸受地形地质条件的制约,共用中间闸室墙,其结构形式和受力条件复杂,采用传统的结构力学方法无法进行精确计算。文章采用有限元方法,建立三维实体有限元模型对长洲三四线船闸中间闸室墙进行了计算分析,得出了不同工况下的中间闸室墙结构的位移及应力分布情况。

Restrained by geographical and topographical conditions, a common wall of mid- dle lock chamber is shared by the third-line and fourth-line shiplock of Changzhou hydro junction.As its structure form and stress conditions are complicated, accurate calculation cannot be made by using conventional method of structural mechanics.Using finite element method,the article established a three-dimensional solid finite element model to calculate and analyze the wall of the middle lock chamber of the third-line and fourth-line shiplock of Changzhou,and thus concluded the displacement and stress distribution of wall structure of middle lock chamber under different workina conditions.
