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。
長洲水利樞紐三線四線船閘受地形地質條件的製約，共用中間閘室牆，其結構形式和受力條件複雜，採用傳統的結構力學方法無法進行精確計算。文章採用有限元方法，建立三維實體有限元模型對長洲三四線船閘中間閘室牆進行瞭計算分析，得齣瞭不同工況下的中間閘室牆結構的位移及應力分佈情況。

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.
