罗家园高层滑升宿舍楼位于北京西便门外护城河拐角处。根据规划要求,定为高层塔式建筑。经多方案比较,综合考虑了使用、施工及材料供应等情况,选用了120°正交三叉形平面方案(图1),用滑模施工。由于采用滑模施工,建筑平面有可能按照大开间 The Luojiayuan high-rise sliding dormitory building is located at the corner of the moat outside Beijing Xibianmen. According to the planning requirements, it is designated as a high-rise tower building. After comparison of multiple schemes, taking into account the use, construction, and material supply, the 120° orthogonal trifurcation plane scheme (Fig. 1) was selected and used for sliding mode construction. Due to the use of sliding mode construction, the building plane may follow a large bay
