Analyzing and determining method for bridge foundation slope stable slope-angle line
The invention discloses an analyzing and determining method for a bridge foundation slope stable slope-angle line. On the basis of the inversion of slope rock-soil physics and mechanics parameters, the action width, embedded depth and load effect modes of a foundation are considered, and the specific position of the stable slope-angle line is analyzed, so that arrangement and engineering design demands for the bridge foundation in a steep slope can be met. The method comprises following technical steps: S1, determining a critical slide surface for the slope parameter inversion; S2, working out the comprehensive cohesive force of a slope rock-soil mass through inverse calculation according to a limit equilibrium state; S3, setting the initial position of the stable slope-angle line; S4, recalculating the slope stability under a bridge foundation loading effect according to the obtained cohesive force of the slope rock-soil mass through inversion calculation; S5, determining whether a safety factor is larger than or equal to a designed safety factor; and S6, obtaining the stable slope-angle line through the analysis.
