城市地下交通联系隧道烟控设计研究初探
Smoke control design for urban traffic link tunnel
摘要：
城市地下交通联系隧道（UTLT）是一种新型的城市地下交通系统，该类隧道由主隧道与多条支隧道组成，且主隧道呈环状或枝状。以含有环形主隧道的UTLT为基础，通过分析其本体结构特点及排烟设计难点，提出了确定UTLT烟控方案的方法与影响因素，以及性能化防火分析时关键参数的设置方法。

Abstract：
The urban traffic link tunnel (UTLT) is a new type of underground urban traffic system, consisting of a main tunnel and several linked tunnels, and the main tunnel is in a loop shape or branched shape. Based on the UTLT with loop main tunnel, through analyzing its characteristics and smoke control design difficulties, provides the method of smoke control and typical parameters setting in the application of performance-based fire protection design.
