The underground is a united garage, with three 17-storey high floors. The floor area of the underground garage is 4,621 square meters, with a floor area of 30641.4 square meters. According to the geotechnical engineering investigation report that range from top to bottom soil foundation depth distribution is as follows: the first layer of tillage planting soil, mainly distributed in the surface area thickness 0.00 ~ 0.80 meters, 2 layers of silt, basic top buried depth distribution of 0.00 ~ 0.50 m, the thickness of 0.30 ~ 4.50 m. The third layer of fine sand is buried deep in the whole area. It is 0.60 ~ 3.20 meters thick and 0.40 ~ 3.50 meters thick. The 4th layer contains the pebble coarse sand, the whole area is covered by the top boundary of the area 1.10 ~ 4.60 meters, the thickness 0.50 ~ 3.40 meters. Layer 5 gravel layer, the top boundary buried deep 1.60 ~ 5.80 meters, the thickness 0.20 ~ 3.00 meters. The main components are coarse sand and gravel, which have high bearing capacity. The 6th - 1 layer of high wind and sandy mud rock, the top boundary buried deep 3.50 ~ 6.80 meters, the thickness 0.50 ~ 0.90 meters. The bearing capacity is high, which can be the foundation of the building. The sixth and second layers are medium wind and sandy clay. This layer is buried deep at 5.10 ~ 7.10 meters, not at the bottom, carrying capacity high, as the building foundations strength layer. The water l
