摘要
我国山地泥石流活动频繁,建筑物防护是山区城镇建设及泥石流堆积扇开发利用中必须解决的问题。了解建筑物在泥石流冲击力作用下的破坏形态,有助于防灾工程设计。利用实际观测数据和泥石流破坏现场调查分析结果,对砖混建筑在受到泥石流冲击力作用下的受力形式及破坏形态进行了理论模拟和计算。在此基础上,进行了墙片的破坏性试验,现场观测墙体在冲击作用下的破坏形态和历程,验证理论模拟结果,提出了加强砖混建筑抵抗泥石流冲击的措施,为建筑物抵抗泥石流冲击设计提供参考。
In recent years,ruinous debris flow disasters occured frequently in Chinese mountain areas.How to prevent and control debris flow has become more and more important in the construction of mountain town and the development and planning of deposit span of debris flow.The reinforced masonry structure is a common construction style in Chinese mountain areas.In all research,first of all,the destruction mode of reinforced masonry structure impacted by debris flow should be found out.This paper simulated and calculated theoretically the bearing load style and the destruction mode of reinforced masonry structure impacted by debris flow utilizing base data from fieldwork and survey.Secondly,the authors fulfilled a destructive test of wall panel to observe the destruction mode and course.The result validated the calculation of theoretical simulation.Finally,several measures to strengthen reinforced masonry structure to defend debris flow was put forward,which can give a reference to construction design defending from disaster.
