Stability mechanical analysis method for cutting masonry retaining wall

The invention is suitable for the technical field of geotechnical engineering, and particularly relates to a cutting masonry retaining wall stability mechanical analysis method which comprises the following steps: constructing a cutting retaining wall geometric model; determining a retaining wall stability problem area, and performing dot matrix discretization on the retaining wall stability problem area; a speed field variable system based on discrete points and inter-point connecting lines is established in combination with the cutting retaining wall geometric model after dot matrix discretization; deriving an optimization equation expression of a retaining wall stability limit analysis upper limit solution; the safety coefficient of the retaining wall is solved, a critical failure mode or a velocity field is obtained, and the stability of the retaining wall is evaluated. According to the method, the defect of bottleneck of artificial hypothesis and global failure mode search in the prior art is avoided, th
