Abstract: The basement of Guangzhou Taikoo Hui project is 283.5 meters long, 154.35 meters wide and 21.5 to 22.5 meters deep. Many supporting forms are adopted in the extra-big and extra-deep foundation pit. The post-cast strip and concrete with durafiber are used in the extra-long concrete structure design to control concrete shrinkage crack. Uplift piles and uplift boltings are used in anti-floating design. The method of perfect combination of hardness with softness and waterproof with drainage is used in water-proof design in order to achieve the aim of keeping the basement dry and comfortable.

Keywords: extra-big and extra-deep foundation pit； supporting form； uplift pile； uplift bolting； hardness with softness and waterproof with drainage
