风致土-结构动力相互作用模型探讨

摘要

Compared with the actual building,intrusive test method has a great influence on the resuits of wind tunnel test considering soil for the small size of the test model.Therefore,there is no report on the wind tunnel test considering soil.The method of synthetic transparent soil test provides a new idea for wind-induced soil-structure dynamic interaction model test.Using transparent soil sets up wind-induced soil-structure dynamic interaction visual model to study the dynamic response and to observe the internal movement of soil-structure and to clear the response and mechanism of wind-induced soil-structure dynamic interaction.%相比于实际建筑,风洞试验模型尺寸较小,已有的介入试验方法,对有土体参与的风洞试验模型结果影响较大.因此,有土体参与的风洞试验未见报道.人工合成透明土试验方法为风致土-结构动力相互作用模型试验提供了新思路.可利用透明土,构造无损可视化动态风致土-结构试验模型,研究风致土-结构动态反应规律,直接观察风致结构、桩体及土体内部运动过程,理清风致地基-基础-结构整体响应规律及机理.
