This work investigates an analysis method for the stability of a three-dimensional (3D) slope with weak zones considering spatial variability on the basis of two-phase random media and the finite element method. By controlling the volume fractions of rock and weak zones, two-phase random media are incorporated into the 3D slope model to simulate the random distribution of rock and weak zones. Then, a rotation of a Gaussian random field is performed to account for the inclination of the weakdoi:10.3390/app11219852 doaj:db1baebb90fc4b64852bf616cd3bc68e fatcat:gh2t7fvcibforghpwo5aobkh5a
