水下隧道工程消防设计系统选择探讨

Discussion on Selection of Fire Protection System Design for Underwater Tunnel Engineering

目前,我国在国标层面还没有专门针对水下隧道的设计规范,国标规范中涉及隧道消防要求的基本为通则条款,若仅仅按国标规范要求进行隧道消防设计,往往不能通过各级消防设计评审要求,水下隧道设计消防系统配置更是一大难题。本文论述隧道消防系统对隧道安全运营及民众生命财产安全的重要性,以及水下交通隧道性质、隧道断面形式对消防设计的影响;通过总结已设计建成通车的典型水下隧道工程实例,同时结合主要隧道消防设计规范要求,提出水下隧道工程行车区域及附属区域消防系统选择方式,以期对水下隧道交通工程消防系统设计提供借鉴和指导。

At present,the design code of our country is not specific at the national standard level for underwater tunnels,the national standard involves tunnel fire protection requirements are basically general provisions,if only according to the national standard for tunnel fire protection design,it often can not pass through the requirement of fire protection design review,and the fire protection system configuration of underwater tunnel design is a big problem.This paper discusses the importance of tunnel fire protection system to the safe operation of tunnel and the safety of people's life and property,and the influence of the nature of underwater traffic tunnel and the form of tunnel section on fire protection design.By summarizing the typical examples of underwater tunnel engineering that have been designed and opened to traffic,and combining with the requirements of the main tunnel fire control design code,the selection method of the fire protection system in the driving area and the attached area of underwater tunnel engineering is proposed,which is hoped to provide reference and guidance for the fire protection system design of underwater tunnel traffic engineering.
