초록

The hazard of excavation may be very high until a supporting system is completely installed. In this paper, an excavation method which uses partially reinforced soldier pile($\square$-shape) inserted by a short length steel bar was proposed and simulated by the finite element method. The reinforcing steel bar is moved down along the stage of excavation to reinforce the stiffness of the supporting system. The result of analysis showed that the risk of failure by bending moment or shear stress could be significantly reduced by the reinforcing effect of the steel bar. The proposed method could be applied to the strut-supporting wall or the diaphragm wall.
