The invention relates to a horizontally stratified rock deformation parameter comprehensive determination method, and belongs to the technical field of rock deformation parameter testing. The method is implemented in a test hole of a construction site and includes the steps: 1) preparing a test component, selecting a test position and make preparations for field test; 2) performing stratified rocksample uniaxial compression test in the test hole and determining the vertical elastic modulus and the Poisson ratio of a horizontally stratified rock; 3) performing vertical bearing plate test and horizontal bearing plate test in the test hole, recording data and drawing a pressure-deformation curve; 4) performing numerical inverse analysis by a commercial finite element calculation program according to stratified rock sample uniaxial compression test results and the vertical bearing plate test and horizontal bearing plate test pressure-deformation curve, and finally determining five deformation indexes reflecting t
