| 摘 要： | 结合黄石板岩山危岩体防治工程,根据现场地形地貌,为拦截落石和危岩削方爆破飞石,提出以拦石坝为主的三级防护布置方案.以落石和爆破飞石的运动特征为基础,探讨基于落石和爆破飞石计算的拦石土坝设计计算方法.首先计算落石爬坡高度,并以此为依据确定土坝高度,根据能量守恒定律计算土坝平均宽度,从而确定土坝的结构和尺寸.进而对土坝的抗落石冲击力、抗滑移和抗倾覆稳定性进行验算,同时对斜坡在施工和坝体砌筑加载情况下的稳定性进行了验算.

| Abstract: | A soil dam has certain ductility and behaves superior to traditional rigid rockfall barrier wall in anti-force capability,but the theory of calculation of rockfall barrier soil dam is still not perfect at present.A 3-grade prevention design of rockfall barrier wall was put forward to intercept rockfall from hazard rock slope and explosive slungshots according to the site topography,combining with Huangshi Banyan mountain unstable rock mass.The calculation of height of rockfall slope and the results would be... |
