城市地下商业街在城市中心区交通状况的改善、提高土地综合利用、增强商业活力等方面,将起着至关重要的作用,也是构建可持续发展城市的一种具体形式。因此,地下商业街和与之相连的地下步行网络在我国是有着广阔的发展前景和巨大的潜力。地下建筑因其所存在的空间介质为岩土,而区别于地面建筑类型,加之消极的传统观念影响,使得安全问题成为其空间开发利用的首要及主要矛盾。因此,如何构筑良好的地下建筑活动空间与安全疏散环境,成为当前研究与设计实践亟待解决的问题。
The urban underground shopping mall will play a crucial role in improving the traffic conditions in the central area of the city, improving the comprehensive utilization of land and enhancing the commercial viability. It is also a concrete form of building a sustainable city. Therefore, the underground shopping mall and the underground pedestrian network connected to it have broad prospects for development and great potential in our country. Because of the existence of geotechnical medium, the underground construction is different from the type of the ground construction, and the negative traditional concept makes the safety issue the primary and main contradiction of its space development and utilization. Therefore, how to construct a good underground construction activity space and safety evacuation environment has become an urgent problem to be solved in the current research and design practice.
