撞击力对大水位差框架码头空间排架结构的影响
|
摘要
本文依托重庆港江津港区珞璜作业区改扩建工程,采用Midas空间有限元软件,对长江上游地区典型的大水位差框架直立式码头进行三维空间数值建模计算,假定其他各工况荷载不变,在不同撞击力作用位置工况下,通过汇总各空间排架的剪力值增量与撞击力的比值表示水平撞击力对各空间排架的影响系数,分析探讨了码头纵撑、横撑、桩径对各空间排架承受船舶撞击力作用的影响情况。
Based on the expansion project of Luohuang terminal area at Jiangjin harbor of Chongqing port, Midas finite element software applied to 3 D spatial value modeling for the vertical framed berth structure with high water head at the upper reaches of the Yangtze River. The increments of shear force on different levels of bents were compared with the impact force to produce an influence coefficient of horizontal impact force on the spatial bents subject to unchanged load and different impacting locations. As for the bents being impacted by ships, the influence of longitudinal braces, transverse braces and pile diameters on the bents were analyzed respectively.
