北京西客站地铁车站的设计与施工

Design and construction of the subway of the Beijing Western Railway Station Complex Project(B. W. R. S. C. P.)

北京西客站地铁车站位于铁路南北站房之间的铁路股道下，车站上面支承着高架候车厅，具有工程量大、地质条件复杂、工期紧、质量要求高、技术难点多等特点。在设计和施工中采取措施解决了地基与荷载不均匀的问题。车站采用明挖法、微差爆破技术缩短了工期。根据工程特点设计应用了新型模板及新式多功能支撑体系。车站立柱设计成Ｃ６０级钢筋混凝土劲性组合柱。大体积混凝土浇筑施工避免了裂缝产生。

The subway station of B. W. R. S. C. P. is located under the railway track in between the north and south station buildings. While above the subway station, it stands the elevated big waiting hall.The subway station is indeed a huge project with a large scale construction work, a complex geological condition, an urgent time schedule. a high quality task requirement and a great variety of technological features. During its design and construction period. measures have been taken to solve the uneven settlement due to the inhomogeneous soil foundation and its heavy loading. An open excavation method and an advanced explosion measure being adopted, thus it has much shortened the working hours of construction. Basing upon its specific design features, a new formwork and a new multifunctional scaffolding system have been used to advantage. Columns of the subway station are designed of the C60 external style R. C. composite column system. Cracks have been carefully eliminated in the mass concrete pouring construction.
