ABSTRACT: Through theoretical analysis and simulation by finite element, a design method of sand pile truck escape ramp is proposed, and two kinds of sand pile types, continuous type and sub-type, are established. By analyzing the variations of speed, acceleration and blocking distance of vehicles, an optimal configuration of sand pile truck escape ramp is gained. Besides, through field tests, the applicability of the proposed design method of sand pile truck escape ramp is verified. The simulation result shows that the combined effect of the blocking effectiveness, the protection for vehicles and personnel, and construction of sub-type truck escape ramp is optimal which meets the requirements of usability and safety of truck escape ramp.
