坠落物为地震时主要的危害之一,也是造成疏散人群伤亡的重要原因之一,也是应急疏散体系的重要因素之一。本文从郑州地区城市中心区的实际调研出发,得出坠落物的控制策略可以从以下几个主要方面控制:1.建筑外构件形式的控制;2.建筑形体的控制;3.疏散道路预留坠落物区域;有效的坠落物控制策略是要结合当地的抗震设防等级,现有建筑外装饰构件,建筑结构与构造,及道路情况综合考虑,才能有效的控制在地震发生时坠落物的危害,控制策略应根据具体的情况而定,因地制宜。
Fall is one of the major hazards of the earthquake. It is also one of the important causes of the casualty casualties. It is also one of the important factors of emergency evacuation system. Based on the actual investigation in the downtown area of Zhengzhou City, this paper concludes that the control strategy of the falling objects can be controlled from the following aspects: 1. The control of the exterior components of the building; 2. The control of the building form; 3. The reserved evacuation roads Crashed area; effective fall control strategy is to combine the local seismic fortification level, the existing exterior building components, building structure and structure, and road conditions into account, in order to effectively control the hazards of earthquakes in the fall, Control strategy should be based on the specific circumstances, according to local conditions.
