The embodiment of the invention provides a three-dimensional wedge analysis method and a three-dimensional wedge analysis system for stability of a slurry groove in a layered foundation, wherein the three-dimensional wedge analysis method comprises the following steps: acquiring a plurality of continuous horizontal slices of soil strips in a layered foundation, and determining a first static balance equation of each horizontal slice of soil strips in the vertical direction and a second static balance equation of each horizontal slice of soil strips in the horizontal direction; determining a first safety factor based on the shearing force and the shearing strength of the damaged surface of each soil strip slice, and determining a second safety factor based on the shearing force and the shearing strength of the side surface of each soil strip slice; based on first factor of safety with first static equilibrium equation solves effective normal force on the soil strip sliced slip surface, based on effective normal force, first factor of safety, second factor of safety and second static equilibrium equation, confirm the implicit expression of synthesizing factor of safety, can consider the layering nature of foundation soil, the size of wedge and wedge side shearing force, can be to the mud slot stability analysis of layering. |
