Abstract Based on feasibility of CFG composite foundation in more than 20 stories of high-rise building, its settlement observation data was analyzed systematically combining with soil condition in Heibei Langfang. Then, subsidence calculation value was compared with measured value, and settlement experience coefficient ψ under different condition values was obtained.
