| Abstract: | There is rich groundwater with complex distribution on the site of Beijing Greenland Center project. The foundation has 5 underground floors, whose total depth is more than 30m. The foundation pit construction period is long, suffering from complex climate conditions, such as clod winter, defrosting in spring and rich rainfall in raining season, etc. Slope protection pile, water stop curtain and soil nail wall are adopted for support and protection of the foundation pit. Foundation pit support and protection scheme is optimized, construction cost is saved and construction schedule is shortened through technological innovation. |
