Abstract：Took the rockfall hazard near the DK27 + 120 section of the Jingying expressway for example, the kinematics combined with the orthogonal test was adopted to select the best combination of kinematic parameters and calculate the control indices for design of protective structure. Three control indices were taken as the testing indices, and five kinematic parameters were taken as the testing factors. The orthogonal test table was used to design twenty-five kinds of schemes, and the numerical simulation tests of rockfall trajectories were carried out. The range analysis was performed to determine the best combination of kinematic parameters. The control indices were obtained based on the optimal parameters. By comparing with the probabilistic analysis results,the feasibility and effectiveness of the proposed method were verified.
