Abstract: A simplified analysis method is proposed by Shanghai Technical Code for Excavation Engineering to evaluate excavation-induced damage of buildings. However, this method can not consider the main factors which affect the deformation of excavations. The simplified calculation formula considering system stiffness, excavation depth, excavation width for the maximum ground surface settlement is deduced by normalizing FEM results. The ground surface settlement profile behind the embedded walls is also provided. The validity of the simplified method of ground surface settlement prediction for excavations retained by embedded walls is verified by calculating several case histories in Shanghai. The ground surface settlement profile is used as the simplified analysis method to evaluate excavation-induced impact on surrounding environment. An example shows that this simplified method is suitable for analyzing excavation-induced impact on surrounding environment.
