青岛地铁1号线跨海隧道通风设计
Subsea tunnel ventilation design for Qingdao Underground Railway Line 1
摘要：
根据工程实际情况分析了跨海区间隧道的特点，结合地铁线路、行车及结构专业资料，研究了纵向通风方案的可行性。以火灾工况隧道风速为评价指标，计算了火灾工况临界风速并进行了隧道风机初步选型。采用SES模拟软件对火灾工况风速进行了模拟计算，结果表明风速达到了临界风速要求。

Abstract：
According to the actual situation of the project, analyses the characteristics of the subsea tunnel, and studies the feasibility of the longitudinal ventilation design scheme combined with the data of underground rarlway line, traffic and tunnel structure. Taking the critical velocity as the evaluation index, calculates the critical velocity and carries out the initial selection of the tunnel fan. Simulates the air velocity of the fire by SES simulation software, and the result shows that the wind speed reaches the critical velocity.
