Abstract

Abstract

As a professional geotechnical numerical software, FLAC3D contains various build-in structural elements, in which the pile element has a potential to simulate anti-slide pile in slope engineering. However, the pile element has too many parameters which have not clarified for anti-slide pile simulation yet. The main parameters used in pile simulation were comparatively analyzed. The comparative analysis shows that the elastic modulus of the pile structural element has little effect on the numerical simulation results, the tangential parameters of the coupling spring have little effect on the stability coefficient of the slope reinforced by anti-slide pile. The internal force distribution of the anti-slide pile is very small, while the cohesion and friction angle in the normal parameters have obvious effect on the simulation results of the anti-slide pile. The larger the parameter value, the greater the slope stability obtained, and the greater the maximum shear force and maximum bending moment of the anti-slide pile. Based on the comparison of the traditional elastic foundation beam method, the parameters of the pile structure element in the anti-slide pile simulation are proposed.
