I. Project Overview The “Jade Garden” project in Shanghai has a “concave” shape. The main building has 1 underground floor and 18 floors above ground. The auxiliary building on the east and west sides is 1 underground floor and 15 floors above ground. The basement floor height is 3m, and the apartment floor height on the ground is 2.8m. There is a basement garage between east and west buildings. The main building is a cast-in-place shear wall structure with partial frame support; the auxiliary building is a pure shear wall structure; the main building is separated from the auxiliary buildings on both sides by seismic joints; there is no basement in the basement; the underground garage is a frame structure; the main auxiliary building and the garage are taken off There are four entrances and exits. Second, the basic program to determine According to the geological conditions and consider the impact on the surrounding environment, choose the pile length of 37m of the pile foundation.
