Anti-floating system of subway station in soft water-rich stratum and construction method thereof
The invention discloses an anti-floating system of a subway station in a soft water-rich stratum and a construction method thereof. The system comprise a station main body structure and an undergroundcontinuous wall, the inner side of the underground continuous wall is provided with a continuous long groove, the outer side of the underground continuous wall is provided with a vertical water stopcurtain, the bottom of a foundation pit is provided with a horizontal water stop curtain and an anti-pulling pile, a structural column of the station main body structure is arranged on the anti-pulling pile, and a pile side reinforcing area is arranged around the anti-pulling pile. The outer side of the underground continuous wall is provided with a wall external reinforcing area, the inner side of the underground continuous wall is provided with a wall internal reinforcing area, the wall internal reinforcing area is arranged in the height range from the lower end of the underground continuouswall to the lower end of a structure bottom plate, and the upper part of a top plate of the station main body structure is provided with a clay backfilling area. The subway station main body structure and the enclosure structure are designed into a unified whole through the embedded design and the arrangement of the reinforcing areas, the self weight of the structure is fully utilized, the side friction resistance of the enclosure structure can be increased, the anti-floating effect and the structural stability of the structure are improved, and the engineering cost is greatly reduced.
本发明公开了一种软弱富水地层地铁车站抗浮体系及其施工方法，包括车站主体结构、地下连续墙，地下连续墙内侧设有连续通长凹槽，地下连续墙外侧设置有竖向止水帷幕，基坑底部设有水平止水帷幕和抗拔桩，车站主体结构的结构柱设置在抗拔桩上，抗拔桩四周设有桩侧加固区，地下连续墙外侧设有墙外加固区，地下连续墙内侧设有墙内加固区，墙内加固区设置在地下连续墙下端至结构底板下端高度范围内，车站主体结构的顶板上部设有黏性土回填区。本发明通过嵌入设计和设置加固区，将地铁车站主体结构与围护结构设计成统一整体，充分利用结构自重，能够增大围护结构的侧摩阻力，提高结构抗浮效果和结构稳定性，而且大大降低了工程造价。
