摘　　要：文章以北京地铁十号线一期工程亮马河站南端主体结构为例,重点研究地下三层三跨中跨盖挖顺作法设计与施工技术,同时针对该工法施工期间存在钢管混凝土柱、中跨盖板上方土体及新改移热力管线的稳定性不好保证的难点和重点,提出了控制钢管混凝土柱柱顶侧移和减小钢管混凝土柱长细比以增加其整体稳定性的解决措施。Taking the main south structure at Liangmahe Station of Line X subway engineering in Beijing as example, this paper focuses on dig practice of middle span cover in underground three-floor three spans and the construction technology.. According to the difficulty and key point that the stability of earth block over middle span cover and new thermal pipeline, solution is provided to improve whole stability by controlling top incline of steel concrete pile and reducing the ratio of column and slenderness of small steel concrete pile.

关 键 词：南端主体结构 热力管线 中跨盖挖顺作法
