| Abstract: | 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. |
