With the large-scale construction of high-rise buildings in recent years, the depth of the excavations has gradually increased. Since deep excavations are usually located in the prosperous areas of the city, and close to various buildings, how to deal with the impact of the construction process such as soil excavation and retaining structure installation on the surrounding environment has become the key issue to the research of deep excavation. The deep excavation of tieback anchored pile retaining structure near the shallow foundation building is studied in this paper. Based on the field observations, the variations of pile deformation, pile head displacement and building settlement were analyzed in detail. Numerical models were established using FEM (finite element method) program Plaxis. A reasonable soil constitutive model was selected by comparing the calculated results with the field monitoring results. Two key parameters, including the position of the adjacent building foundation and the additional stress of the foundation, were discussed, in order to obtain the disturbance behaviors between the anchored pile wall excavation and adjacent building. The research results showed that the concrete supports and the crown beam would increase the influence region of the excavation corner effect while restraining the deformation of the retaining pile head. For excavation unloading issues, the calculated results obtained from Hardening-Soil（HS） model are more accurate than those from the Mohr-Coulomb（MC） model. The primary influence zone locates at the region within 2.5He(excavation depth) behind the retaining structures. The maximums of average building settlements and building inclinations are 0.6Heand 1.1He. The positions of the maximum of average building settlement and the ground surface maximum settlement are identical. The position of the maximum of inclination is located at the inflection point of the ground settlement curve. For this project, when the buried depth of the building foundation is 2.5 m and the distance between the retaining pile of the deep excavation and the center of the building changes within the range of 7.5～52.5 m, the maximums of the average settlement and inclination of the building are about 8.3 mm and0.00025, respectively. Furthermore, for each additional floor, the settlement and inclination of buildings increase about 0.9 mm and 0.7×10-4, respectively, and the maximum lateral displacement of the retaining structure of the deep excavation increases by 1.4～2.0 mm, of which the increment increases with the number of floors.
