Numerical Simulation and Design Optimization of Anchor Bolt-Sash Girder Support for Expansive Soil Cutting Slope

Abstract:

The reinforcement of expansive soil cutting slope has been a difficulty for the construction industry. This study selected Wanyi Expressway as the construction background and used finite difference method for the numerical simulation and design optimization of expansive soil cutting slope reinforced by sash girder anchor bolts. Calculation results show that the cutting slope ratio is closely related to the stability of the expansive soil cutting slope and that the length, set angle, and vertical spacing of the anchor bolts significantly influence the deformation of the cutting slope. The original design plan was optimized according to the calculation results, and a positive effect in plan execution was achieved. This study may serve as a reference for other similar construction designs.
