This paper presents the influence of differential settlement analysis for the single and multi-combined longitudinal precast box culvert subject to loading conditions and deferential settlement. These precast box culvert was investigated with limit deformation for single and multi-box culvert which is connected using screw bolt formed a rigid and flexible connection in a certain non-uniform settlement interval. Farther over, the finite element method was used to analyze the numerical solution of the problems under the condition of assembled of the standard three dimensional double box culvert with soil mass and floor reaction under different loading conditions located on right side soil of box culvert which is using brick element in ABAQUS software. The culvert was modeled as per Chinese Code of standard parameters using three dimensional solid elements having geometric and material non-linearity. Finally, the deformation foundation resistance of the box culvert is the space between the multi-box culvert joint and the single box culvert length. Besides the screw bolt connection have a negative impact on the performance of the side wall of combined longitudinal box culvert.
