摘要
广东丘陵山区广泛分布花岗岩,而花岗岩往往发育成许多球状风化体(孤石),易发生失稳滚落,对山下建构筑物以及人员安全造成威胁。本文针对广东省河源市龙川县上坪镇石湖村村委会所在地东北侧一带坡面孤石开展调查,通过分析其发育分布特征,对坡面孤石进行稳定性评价,利用Rockfall软件对孤石运动轨迹和能量曲线进行模拟,以更有效地设置拦石墙、被动防护网等拦截上部的孤石。
Granite is widely distributed in the hilly mountainous areas of Guangdong Province,and granite often develops into many spherical weathered bodies(boulders),which are prone to instability and rolling,posing a threat to the safety of structures and people below the mountain.In this paper,a survey was carried out in the northeast area of Shihu Village,Shangping Town,Longchuan County,Heyuan City,Guangdong Province.By analyzing the characteristics of development and distribution,the stability of the boulders was assessed.Rockfall software was used to simulate the movement trajectory and energy curve of the boulders,so as to more effectively set up rock retaining walls and passive protective networks to intercept the upperrocks.
