摘要
为解决隧道卫生环境和火灾排烟问题,本文依托海口文明东越江通道工程,分析了隧道通风方式选择、卫生标准取值、纵向排烟的临界风速修正等对隧道行车环境、消防安全的影响。利用SES程序对多匝道隧道进行通风计算,复核各工况风量分布以及风机配置,为多匝道地下互通隧道的通风排烟系统设计提供借鉴和参考。
To solve the problems of tunnel sanitation and fire smoke exhaust,based on the Haikou Civilized East Crossing River Passage Project,the impacts of tunnel ventilation mode,sanitary standard value and the critical wind speed correction of longitudinal smoke exhaust on tunnel driving environment and fire safety were analyzed.The SES program was used to make the ventilation calculation of the multi-ramp tunnel,and to review the air volume distribution and fan configuration in each working condition,aiming to provide reference for the design for the ventilation and smoke exhaust system of multi-ramp underground interconnection tunnels.
