Research on Pre-Reinforcing Composite Foundation with a Shield Tunnel Under-Passing

Abstract:

This paper analyzes the per-reinforcing effects of composite foundation with a shield tunnel under-passing, and tries to find the regularity in soil foundation improvement under such conditions. The paper establishes piles-soil separation model using software FLAC3D in a finite difference method and research the influence of effective pile length and effective replacement rate on ground deformation under the condition of shield-driver tunnel excavation. there does exist the optimum reinforcement range about pile length and replacement rate between the surface and the top of tunnel. Moreover this can offer reference for similar projects to a certain extent.
