Abstract

Determining avoiding routes is a key specification for highway location in mountain areas. According to the kinematics theory, formulae are derived for calculating distance of rockfalls on loose slope, taking into consideration the influence of rotation during collision. Using the software Rockfall, a model of field test is constructed. Results of software modeling, formula-based calculation and measurement are compared to verify feasibility of the formula that has guiding significance for determining avoiding routes. Typical factors influencing distance of rockfalls are analyzed to lay foundation for further research.

Key words： influencing factor; kinematics theory; numerical simulation; rotation; slope rockfall
