The paper describes the study for optimum positions of sensors in the shaking table test for subway station structure in soft soil. The deformation features of subway station structure under the transverse vibration is proved by three-dimensional FEM analysis. On the base of the result
it is determined that includes the scope of section that satisfies the plane strain rules and the position of the main observation section. The deformation tendency of station structure is analyzed by plane strain FEM and the optimum positions of sensors in the observation section is determined. The method is proposed on the premise of satisfying the demand of basic information
which can optimize the distribution of available sampling passages. The achievements guarantee the success of the test and can be referenced by the same type test.
