Research on Numerical Simulation of High Filling Culverts Foundation Failure Mode

Abstract:

Foundation failure mode of high filling culverts involves calculation theory and method of subgrade bearing capacity, and it has great theoretical and practical values. After model of the culvert has been established, finite difference method will be used to do the numerical simulation in FLAC3D. Reaserch suggests that traditional Terzaghi/Meyerhof failure mode are not suitable for relatively deep buried subgrade of high filling culvert. Foundation failure of high filling culvert is caused by difference in stiffness and earth press, which result in settlement difference, and then forms subsidiary shear stress on the sliding surface. When stress value reaches shear strength of the foundation soil, shear failure occured.
