| Abstract: | In this paper the factor and the provision of the surface settlement induded by shield driven method are analyzed. With an elasto-plastic finite element program, the immediate surface settlement for the experimental section of Shanghai Metro has been predicted. Based on the finite element analysis and the data of the field measurement, a practical formula for estimating surface settlement of Shanghai Metro is proposed, which can serve as a reference in controlling surface settlement during the construction. |
