| description | The invention belongs to the technical field of underground excavation construction of underground structures, and discloses a method for constructing an underground station under facilities sensitive to settlement. Foundation pits are constructed on the two sides of the facility sensitive to settlement, and the foundation pits are excavated to the position of a top plate; top longitudinal pipe roofs and side longitudinal pipe roofs are arranged in the foundation pit along the outer contours of the top plate and part of the side walls of the underground station in a downward penetrating mode; the foundation pits on the two sides continue to be excavated to certain positions below the pipe roofs, and horizontal advanced reinforcement is conducted on soil bodies within the set height range below the pipe roofs in the foundation pits; a soil body with the set height range below the pipe roofing is excavated longitudinally in a segmented mode, a side enclosure and a middle steel stand column are constructed in th |
