基于ANSYS有限元分析的高桩码头施工期气温控制研究

On construction temperature of high-pile wharf based on ANSYS finite element analysis

提出从面板角点位移、上部结构受力和基桩受弯等方面实施多目标控制设计思想,并通过ANSYS有限元建模分析,详细地研究了码头面板无温差和有温差两种工况下,高桩码头结构在不同施工期气温条件下的变形和受力变化规律。由此确定施工期气温控制为:面板无温差时,施工期气温控制在11.1℃以上,能够确保角点纵向位移满足规范要求;面板有温差时,则施工期气温需高于21.4℃才能满足要求。

This paper proposes the idea of multi-objective control with the displacement of corner points,internal force of upper structures and base piles flexural controlled.With the help of building ANSYS finite element model,researches the laws of transformation and the force changes of wharf structure under different construction temperatures when the panel suffers a temperature difference or not.Through these laws,conclusions can be drawn that only when the construction temperature is higher than 11.1℃,can the displacement of corner points meets the regulatory requirements when there is no temperature difference of the panel.And the value should be higher than 21.4℃when there is a temperature difference.
