摘要： 介绍了国内地下建筑工程常用的施工方法及其特点和适用性。以长春地铁解放大路站工程为例，论述了改进技术“一次扣拱暗挖逆作法”与传统PBA（洞桩法）法相结合应用于地下建筑工程的修建，综合比较其他工程实践，一次扣拱暗挖逆作法在施工效率、工程造价、土体沉降方面较传统PBA工法有着更大的优势，适用于繁华城市中心区地质稳定性差的地下建筑工程施工。

Abstract: The common construction methods and their characteristics and applicability of underground construction engineering are introduced in this paper. A new underground construction method, which is the combination of traditional PileBeamArch (PBA) method and improved “TopDown Bored Excavation with CastinSitu Arch” method for the Liberation Boulevard Subway Station Project in Changchun, is introduced. The new construction method is compared with other conventional construction methods and the results indicates that, it has the advantages in construction efficiency, cost effectiveness and ground subsidence control over the traditional PBA method. The new method has the special advantage in the urban underground construction with poor subsurface conditions.
