In a construction site in downtown Shanghai, the construction site is only about 2,500 square meters. The required building area is 11,254 square meters. The selected plane size is 40 x 36 meters, the main part of the column net is (20+20) x 7.2 meters, the height is six layers, the two sides are twelve layers, the building height is 33.9 meters, and the architectural shape is shown in the title photo. I. Engineering geology A total of three exploration sites are arranged on the construction site for earth exploration and static sounding. The general values of the main physical and mechanical properties of soil are shown in Table 1. Exploration shows that, except for the surface layer of yellowish-brown sub-clay with a thickness of 0.5 to 2.0 meters, all of them are highly compressive, silty clay soil layers.
