Research on Rockfall Risk Assessment and Decision-making for Protective Measures Based on Trajectory Calculation
Rockfall is one of common geological hazard.In order to explore and verify a simple and reliable risk assessment method,in this paper,according to the needs and characteristics of the project itself,a simple trajectory calculation method is chosen to evaluate the rockfall risk.We programmed the kinematics formula and discussed the reasonable values of the calculation parameters.A large number of calculation data simulate the characteristics of rockfall in the process of slope movement,give the evaluation result of high rockfall risk,and formulate the prevention and control strategy which should be based on active protection.
