关于冰荷载对桩基结构作用的探讨

Investigation on the Action of Ice Load on the Piled Structure

本文描述码头结构设计中应考虑的冰层对桩基结构的几种主要作用形式,着重论述冰层对桩基撞击力的计算,并结合现场观测的现象描述冰层与桩基撞击时几种冰层破坏的过程。关于冰速对撞击力的影响以及撞击力计算公式的选取,笔者提出了自己的见解和推荐公式。

For the action of ice load to the piled structure, this paper gives its importance in the wharf structural design and puts emphasis on the computation of impact load of ice layer on the structure. Combining with in situ observations, the author has taken notice of the whole process of ice breaking condition when it struck the piled structure. In regard to the effects of impact load the author gives an opinion on the computing method and puts forward his recommended formula.
