与胸墙连接的沉箱外墙及隔墙内力计算模式探讨

Discussion of Calculation Model of Outer and Separation Wall Connected with Breast Wall of Caisson

对于大型沉箱重力式码头,沉箱外墙及隔墙的内力计算结果与计算模式的选择有关。按现行有关规范可不考虑上部胸墙对沉箱的约束,但构造要求需符合固接处理条件。结合某沉箱重力式码头工程,在考虑胸墙约束的模式下,对沉箱外墙及隔墙的内力计算,按不同模式进行对比分析,并给出相关结论和建议。

For the caisson gravity quay, the inner-force of the outer wall and separation wall is very important and the calculated result is associated with the calculation model used. According to the current code concerned, the constraint of breast wall is ignored, but the structure should conform with the consolidation treatment condition. Under considering the constraint of breast wall, the comparison analyses on the inner-force of the outer wall and separation wall are made according to the different models and the relative results and suggestions are given.
