Based on the measured data of foundation pit project in sandy stratum of Dongshangze subway station in Shijiazhuang,a numerical calculation model was established to analyze the influence of excavation depth,relative position and foundation pit deformation on the deformation of existing pipe rack in the sandy soil site,and a deformation database of existing pipe rack was obtained.Based on this database,a semi-empirical theoretical prediction method for horizontal displacement of existing pipe rack was established.The applicability of the method is verified by a large sample database.
