The invention discloses a crustal stress inversion analysis method, belongs to the technical field of crustal stress inversion, and can solve the problems that an existing crustal stress inversion method is not matched with the actual situation in the engineering field, and the operation difficulty is large. The method comprises the following steps: S1, determining x axial stress, y axial stress, vertical principal stress and xy surface shear stress of each test point under an xyz coordinate system according to test information of a plurality of test points at different underground depths of a to-be-tested area; s2, according to the x axial stress, the y axial stress, the vertical principal stress and the xy surface shear stress of each test point, the z axial stress, the xz surface shear stress and the yz surface shear stress of each test point are obtained by using an infinitesimal body theory; and S3, according to the depths, the x axial stress, the y axial stress, the z axial stress, the xy surface shear
