摘要

鉴于模型试验是研究冰激结构振动特点和机理的一种非常有效的方法和手段,本文以某桥墩为背景,通过一修正的动冰力模型试验相似律设计了一桥墩模型,应用DUT-1模型冰,模拟了不同冰速下冰-桥墩动力相互作用过程,并实测了冰力和桥墩各测点处的响应。进而得到了一些有价值的试验现象和试验结果,这将为寒冷区域实际冰工程的建设提供一定的借鉴意义,同时可为冰激结构振动的发展提供探索性的意义,也能够在一定程度上完善室内冰激振动模型试验。

Abstract

As model test is an effective method to study the characteristics and mechanism of ice-induced vibrations of structure. In this paper, based on a modified similitude law, a laboratory test is performed for the simulation of ice-induced vibrations of a pier structure , in which DUT-1 model ice sheet are driven by the trailer at different velocity. Both the ice sheet time histories and the response of pier are measured. According to the test phenomenon and measured results, some valuable conclusions are obtained. Therefore, this ice- induced pier vibration model test can provide references for the progress of real ice engineering in cold area., and is a suitable way to study the ice-structure interactions and ice-induced vibration . It also can make the model test develop more perfectly.
