摘要
为了保证灾害发生时人员的安全疏散,隧道安全疏散通道的合理布局至关重要。首先收集了国内外49座公路隧道案例,统计分析了公路隧道常用的安全疏散方式以及它们的特点和适用范围;针对公路隧道最常用的横通道疏散方式,深入分析了横通道间距分布区间、发展趋势以及与隧道长度之间的关系。在案列统计分析的基础上,以某水下公路隧道为例,进行了安全疏散通道设计并采用Building Exodus软件验证了其合理性。本文研究成果为公路隧道安全疏散通道的合理确定提供了参考依据和借鉴。
It is important to choose reasonable safe evacuation channels to make sure personnel security. The common safe evacuation ways and their chrematistics and scope of application are attained by statistical analysis of 49 tunnels. For the cross channel, the commonly used evacuation method for road tunnel, the distribution range and development trend of its gap, and its relationship with tunnel length are analyzed. Based on the case analysis, the safe evacuation method for a subaqueous road tunnel is designed, and its rationality is proved by using the＆quot;Building Exodus＆quot;. It provides reference for the design of safe evacuation methods of road tunnels.
