Influences of Vehicle Loads on Braced Excavation in Soft Clay

Economic development and urbanization give rise to the excavation complexion, and higher requirements on design work are put forward. The risk of excavation in soft clay area is high and the design shall be comprehensive. While in practice, the dynamic characteristic of vehicle loads is seldom calculated. In this paper, conventional one-side plane method (beam on elastic foundation method) and three-dimensional finite element method were adopted to analyze the effects of vehicle loads on the retaining strutting system of braced excavation. Moreover, the reinforcement scheme of excavation after collapse was given as references for similar situations.
