Rock-fill dam deformation field reconstruction method based on Bayesian Kriging and partition optimization

The invention relates to the technical field of water conservancy and geotechnical engineering, and particularly discloses a Bayesian Kriging and partition optimization-based rock-fill dam deformation field reconstruction method, which comprises the following steps of establishing a three-dimensional finite element model; initial material parameters of the rock-fill dam are obtained; performing parameter inversion of the rockfill material constitutive model; performing three-dimensional finite element simulation by adopting the inversion parameters to obtain an inversion deformation field; carrying out regional division on the dam body based on the material partition, and obtaining a residual data set of each sub-domain; analyzing and checking each sub-domain residual error, and fitting to obtain a semi-variance function; calculating a semi-variance function of finite element simulation; establishing a spatial model of each sub-domain; calculating the optimal weight of each sub-domain based on the optimal wei
