球状风化花岗岩边坡滚石灾害防护设计研究
The protection design for rockfall hazard of spherical weathering granite slope

以闽东南典型球状风化花岗岩边坡滚石灾害为对象，采用工程地质分析与数值模拟相结合，研究边坡滚石的运动轨迹、停滞概率和冲击特性等成灾规律；模拟分析坡形坡率优化、平台缓冲介质和滚石拦挡措施的减灾机理和工程效果；最终提出一套系统的边坡滚石灾害防护设计方案.
Based on the typical rockfall hazard of spherical weathering granite slope located in southeast Fujian，the disaster laws which reveal trajectory，stagnation probability and impact characteristic of rockfall were researched with engineering geological analysis and numerical simulation. Disaster-reduction mechanism and engineering effects of the optimization for the profile of slope，platform-buffering medium and rockfall barrier were simulated and analyzed. Eventually，a systematic design scheme of rockfall hazard protection was put forward
