大跨径斜拉桥火灾下风险防范措施研究

Risk Prevention Measures for Long-Span Cable-stayed Bridge Under Fire

为了研究制定斜拉桥火灾作用下的风险防范措施,以某斜拉桥为工程对象,结合桥梁发生汽车燃烧火灾事故特点,制定斜拉桥火灾事故防护体系图,在桥梁关键部位设置各类标志措施以实现火灾下的交通疏散。建立斜拉桥抗火救援保障体系,布置监控报警系统和桥梁应急显示系统,关键部位设立消防灭火措施,保证了火灾下斜拉桥的安全运营。

To formulate risk prevention measures of cable-stayed bridge under fire, taking a cable-stayed bridge as the engineering objects, combining with the characteristics of bridge car burning fire accidents and cable-stayed bridge of fire protection system, ＂all kinds of flag measures in bridge key parts to realize traffic evacuation under fire. The establishment of a cablestayed bridge resistance to fire rescue security system, arrangement of monitoring alarm system and bridge emergency display system, key parts to set up the fire extinguishing measures, ensuring the safety of the cablestayed bridge under fire.
