The living area of a company in Tianjin Dagang District is located on the west bank of Bohai Bay, northeast of Beidagang and about 8km away from the coast. Unexplored, it broke ground to build four residential buildings in early March 1984 and completed the work in October. When he started living in October 1985, he discovered that there was super settlement and obvious tilt in the building. From November to December of 1986, the author participated in the survey work of the disease building and is now analyzed from the perspective of geotechnical engineering survey. If anything, please criticize and correct me. I. Overview Disease buildings 101-104, are four-storey buildings, length 60m, width 8.9m, height 10.5m, said 84 to 1 type. Each building is divided into five units, brick-concrete structure, seismic columns in the building, ring beams on each floor, pit excavation depth 1.2-1.4m, base of raft, thickness 250mm, width
