Earth excavation method for foundation pit groups with different depths on two sides of operation subway
The invention discloses an earth excavation method for foundation pit groups with different depths on two sides of an operation subway. A deep foundation pit and a shallow foundation pit are arranged on the two sides of the subway respectively. The earth excavation method comprises the following steps that the bottom elevation of the shallow foundation pit serves as a depth boundary, and the deep foundation pit is divided into a shallow area higher than the depth boundary and a deep area lower than the depth boundary; earth excavation is carried out on the shallow foundation pit and the shallow area of the deep foundation pit, earth in the shallow area of the shallow foundation pit and the shallow area of the deep foundation pit is horizontally partitioned, and block-by-block, layered and relative excavation is carried out in the direction from the position away from the subway to the position close to the subway; and earth excavation is carried out on the deep area of the deep foundation pit, horizontal partitioning is carried out on the deep area with the shallow area as the standard, and block-by-block and layered excavation is carried out in the direction from the position away from the subway to the position close to the subway. The earth excavation method solves the technical problem of lateral deformation caused by unbalanced excavation on the two sides of the subway.
本发明的运营地铁两侧不同深度基坑群土方开挖方法，地铁两侧分别设有深基坑和浅基坑，包括如下步骤：以所述浅基坑的底标高为深浅分界线，将所述深基坑分为高于所述深浅分界线以上的浅层区以及低于所述深浅分界线以下的深层区；对所述浅基坑以及所述深基坑的浅层区进行土方开挖，对所述浅基坑和所述深基坑的浅层区的土方进行水平分块，由远离所述地铁向靠近所述地铁的方向进行逐块、分层、相对开挖；对所述深基坑的深层区进行土方开挖，对所述深层区以所述浅层区为基准进行水平分块，由远离所述地铁向靠近所述地铁的方向进行逐块、分层开挖。本发明解决了地铁两侧不均衡开挖导致的侧向变形的技术问题。
