| 摘 要： | 在芦山地震灾区滚石调查中发现,高陡斜坡若存在平台或近似平台,滚石危害会降低很多,因此可以考虑采用平台来作为滚石的一种防治措施。在对芦山地震灾区王家后山典型滚石运动轨迹进行分析计算的基础上,研究滚石在平台前后的运动轨迹和冲击力变化,结果表明:典型滚石在经过平台位置后,弹跳高度、冲击力以及动能都显著降低。

Research on Movement Characteristics of Typical Rolling Rocks in Lushan Earthquake-stricken Area |
| |
| Abstract: | The investigation on rolling rocks in Lushan earthquake-stricken area found that if there is any platform or approximate platform on the high and steep slope, rock damage will be reduced greatly.Therefore, it’s considered to use platform as prevention and control measures for rolling rocks.Based on the calculation and analysis of motion of rolling rocks in the Lushan earthquake-stricken area, study of the rolling rocks trajectory and impact of change before and after the platform, the results show that the typical rolling after platform position, bounce height, impact and kinetic energy are significantly reduced. |
