摘要
崩塌落石作为常见地质灾害之一,为探索验证简便可靠的风险评估手段,文中根据工程自身需求和特点,选择形式简洁的轨迹计算法评估落石风险.通过运动学公式进行程序化设计,讨论计算参数的合理取值,用大量计算数据模拟落石在坡面运动过程中的特征,给出落石风险评估结果,并制定出以主动防护为主的防治策略.
Abstract
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.
