摘要
通过对传统暗挖工法的解析,结合工程实践,提出一种新的用于修建大型地下建筑工程的暗挖工法——一次扣拱暗挖逆作法,阐述新工法的技术核心和要点,在北京地铁黄庄站的实践,以及应用发展前景。
On the basis of analysing traditional tunneling methods and engineering practice, a new technology of topdown bored excavation with cast-in-situ arch for large-scale underground projects is put forward. Key techniques of the new method and its application in Huangzhuang Station of Beijing metro are descried. Application prospect of the method is highlighted.
