摘要
文章根据南京纬三路长江隧道的建设条件,对工程总体设计中的几个难点问题及解决方案进行了研究与介绍,其中通过双管双层盾构隧道X型地下布线方案实现交叉道路的互通疏解,以及在双层盾构隧道内设置上下层共用排烟道的布置方式均为国内外首次采用。这两项新技术的应用不仅合理解决了本工程的总体设计难题,而且极大地提高了隧道逃生救援的及时性和便捷性,对类似工程有一定的借鉴作用。
The paper studies several difficult problems and their solutions for the general design of Nanjing Weisanlu Yangtze River tunnel. The x-shape layout of two crossed underground tubes of shield tunnels to facilitate traffic organization, the two-storey lining of shield tunnels accommodated for two-way traffic and the common smoke exhaust duct for two storeys of the tunnel are for the first time adopted in the world. The innovations not only solve the difficult problems for the general design but also improve the convenience of escape and rescue of passengers in emergencies.
