封仓盖板对圆沉箱内力的影响分析

Analysis of influence of hatch cover on cylindrical caissons′ internal force

文章采用空间有限元分析方法,在不同的外荷载下,针对不同的封仓盖板条件,对圆沉箱的内力进行对比,综合分析封仓盖板对沉箱各部位内力的影响,为圆沉箱的设计优化提供借鉴。

With finite element analysis method, under the different loads, according to different conditions of the hatch cover, the internal force calculating results of the cylindrical caissons were compared in this paper, and the influence of hatch cover plated on each part of the caisson was analyzed. The results may serve as a reference for the optimization design of circular caisson.
