Spatial Effects of Lateral Deformations of Supporting Structure of Deep Excavation

By C. L. Li, Y. M. Feng, F. Yang and P. Hagan


In order to improve the design theories of the supporting structure, based on a deep excavation project, FLAC3D was used\ud to simulate the spatial effects of the lateral deformation happened in the process of the deep excavation for the diaphragm\ud wall. The results showed that there would produce the spatial effects in both the horizontal and depth directions; the\ud spatial effects of the lateral deformations were different for the long and short sides; and the spatial effects of the lateral\ud deformation were only obvious in a certain distance from the bottom to the top of the deep excavation. The nonuniformity\ud coefficients of the lateral deformations were modified, and according to the supporting forms and supporting\ud parameters this study provided some theory basis for the supporting design of the deep excavation
