基于重大危险源风险评价的城市消防供水系统优化研究-安全工程专业论文.docxVIP

沈阳航空航天大学上程硕士学位论文摘要 沈阳航空航天大学上程硕士学位论文 摘要 随着城市化进程的逐步加快，城市的火灾危险性不断加大，并且由于城市消防供水 系统的数量不足和布局问题常常导致火势不能得到有效控制，最后酿成大灾。本文就是 通过对城市消防供水系统现状的分析研究，在重大危险源调研数据的基础上，结合消防 部队灭火救援实际需要探讨一个针对城市消防供水系统优化布局的可行性方法，为解决 城市供水系统难题提供解决途径。 本文以2005及2009两年来沈阳市重大危险源调查数据为基础，主要从城市消防供 水系统的数量和布局两个方面米进行研究。首先分析了当前城市消防供水系统的主要形 式和特点，然后结合消防部队火灾扑救实际情况，供水主要形式，以城市一次性灭火进 攻用水量为出发点对城市消防供水系统进行数量研究。在消防供水系统布局方面，考虑 到市政消火栓等消防供水系统的保护半径等斟素，通过建立最短路径矩阵的方法确定重 大危险源与消防供水系统的最大覆盖与最优覆盖，从而确保城市消防供水系统的设计实 施既能满足实际需要，又有很高的经济效益。 最后沈阳市新城子区为例，通过上述模型对城市消防供水系统进行优化布局。 关键词：重大危险源：消火栓：消防水源：最短路径：优化布局 沈阳航空航天人学工程硕士学位论文Abstract 沈阳航空航天人学工程硕士学位论文 Abstract With the gradual speeding up the urbanization process，the city fire risk increases，Because the City Fire protection water supply are often inadequate and layout issues caused the fire can not be effectively controlled，and it becomes final catastrophe．This thsis， through the analysis of City Fire protection water supply based on major hazard installations survey data combined with the practical needs of fire fighting and rescue force of a City Fire protection water supply for the city of the feasibility of optimizing the layout method will provide a solution．to solve the problems of City Fire protection water supply In this paper,based on 2005 and 2009 two years of major hazard installations survey data in Shenyang，Mainly studied from the City Fire protection water supply both the quantity and distribution．First analyse the current City Fire protection water supply main form and features and then combine with actual fire fighting，main form of Water supply,attacking the city a one-·time fire--fighting water as the starting point to study the city the number of City Fire protection water supply．In layouting of Fire protection water supply,we can Take the municipal water supply system into account for fire hydrant protection radius and other factors，The shortest path through the establishment of major hazard installations and fire protection water supply determine the source largest service coverage
