摘　　要：城市避震疏散通道的震后通达性直接关系到能否在第一时间安全转移受灾群众及顺利开展救灾工作。以济南市杆石桥街道为研究对象,考虑到震中沿街建筑的倒塌影响,借助空间句法进行道路系统的抗震可靠性和通达性评价,并提出优化建议。经分析,杆石桥街道建筑密度较高,高层建筑多布局于道路交叉口,均对街区道路的避震疏散功能有一定威胁,且老城区本身避震疏散网络规划不足、存在较多救灾“死角”。随着城市的发展和更新,大多中心城区的规划年代久远,原有避震疏散网络已不能满足需求,近年来自然灾害频发,中心城区的避震疏散通道亟待进行整体评价及优化。The post-earthquake accessibility of urban evacuation roads is directly related to whether the affected people can be safely transferred in the first time and whether the disaster relief work can be carried out smoothly.Taking the Ganshi Bridge Street in Jinan City as the research object,considering the impact of the collapse of buildings along the epicenter,the seismic reliability and accessibility of the road system were evaluated with the help of spatial syntax,and optimization suggestions were put forward.After analysis,the high density of buildings in the street and the layout of high-rise buildings at road intersections all pose a certain threat to the seismic evacuation function of block roads,and the old city itself has insufficient planning of seismic evacuation network and more "dead ends" for disaster relief.With the development and renewal of the city,most of the central urban areas have been planned for a long time,and the original seismic evacuation network can no longer meet the demand,and in recent years,natural disasters have been frequent,and the overall evaluation and optimization of seismic evacuation channels in the central urban area need to be carried out urgently.
