The Important Problems about Gu Lou Underground Interchange Project in Nan Jing

南京鼓楼地下立交工程建设的若干问题

Therefore, the study on the underground interchange tunnel has important academic and real meaning.

因此, 研究地下互通式立交工程的施工方案具有重要的理论和实际意义.

Different from building a single tunnel, building interchange tunnels will encounter many Problems that does not exit during building a single runnel. Furthermore, the underground interchange tunnels is at its early stage, so corresponding design and construction experiences are seriously penurious.

与修建单一的隧道不同，要在地下修建多条互通立交的高速公路隧道，将会遇到各种单一隧道中不存在的问题，而且目前这方面的设计、施工均没有直接的经验，难度将会大大增加。
