A New Subway Station Construction Method: Top-down Boring with Cast-in-situ Arch

摘要

With the speedy development of urban mass transit in China, more and more building environment problems are coming forth in many cities. How to choose available construction method to fast, safely and economically build subway engineering is worthy to be urgently studied. A new-type subway station construction method called top-down boring with cast-in-situ arch is presented through a large number of design calculations, research and analysis, on the basis of conscientiously analyzing traditional tunneling methods and engineering practice. Some advantages of this new method are briefly introduced, compared with the shallow mining methods for underground engineering construction, as well as its application in subway engineering. According to further study, this new construction method will be widely used in underground engineering projects. At the same time, the relative theory of this new method will be validated and promoted.
