Abstract以云南东川蒋家沟实际观测资料为基础,研究砖混结构建筑墙体在受到泥石流体中携带的大石块冲击力作用下的受力形式及破坏形态;在此基础上,进行了砖混建筑结构墙体模型试件的破坏性实验,现场观测试件在平面内和平面外两种冲击力作用方式下的破坏形态和历程,采集其动态位移、振幅及主振频率数据,经计算分析得出结构动态响应模式。
Other AbstractIn recent years, ruinous debris flow disasters erupted frequently in Chinese mountain areas. How to prevent and control debris flow has special importance in the construction of mountain town and the development and planning of deposit span of debris flow. It's very important to simulate impact load of debris flow effectively and to investigate dynamic response of architectures under dynamic impact of debris flow, all of these research are necessary to the design of construction mitigation measures. This paper chose Jiangjiagou of Yunnan province, in China as research region. Utilizing based data from fieldwork and survey, this paper simulated and calculated theoretically the bearing load style and the destructed shape of reinforced masonry construction impacted by debris flow. Secondly, the authors fulfilled a destructed impactive test of a set of reinforced masonry wall models. During experiment, the destructed shape and course of model were observed and the dynamic displacement data and main natural frequencydata of model were collected using IMHE Impact Data Collecting System ( IMHE IDCS). According to failure criterion and experiment data, the anti-impact behavior of researched architecture was deducted.
