城市大型地下快速通道建设的关键技术
Key Technologies of Urban Large Underground Express Passage Construction
进入21世纪，世界经济的迅猛发展加速了城市化建设。随着城市密集度的提高和高层建筑的不断增加，地面可利用空间越来越稀缺。构建以城市大型地下快速通道为主体的多维度、立体化交通网络是解决该问题最有效的途径，同时开发地下空间非开挖施工及互通互联技术在应对土地资源紧张、交通堵塞、能源增耗、环境污染、房价上涨等方面发挥着重要作用。
In the 21st century， the rapid development of the world economy has accelerated urbanization. With the ever increasing urban density and high-rise buildings， the available space on the ground becomes scarce. Constructing a multi-dimensional and stereoscopic traffic network with urban large underground express passage as the stem can be the most effective way to solve the problem. The trenchless construction and interconnection technology of underground space play vital roles in solving problems including land shortage， traffic congestion， increased energy consumption， environmental pollution and rising house prices.
