The database of 58 over-19-meters deep foundation pits helps to study the horizontal displacement of supporting structure and the surface settlement behind diaphragm wall. By fully data mining, the curve feature, and normalized maximum value of the horizontal displacement are obtained. The curve feature, maximum location and the influence range of the surface settlement behind diaphragm wall are also analyzed. These conclusions can be used in estimating the deformation, optimizing the design and guiding the construction for ultra-deep foundation pit.
