【摘要】 采用理论公式法和Rockfall程序数值模拟法,对四川省汶川地区裕丰岩上部失稳危岩体孤石的稳定性进行了研究。结果表明:在自然、地震和暴雨工况下,暴雨工况是危岩体孤石失稳的主要因素。孤石在下落时运动特征具有随机性,通过对孤石弹跳高度和运动能量的分析,可以更有效地对危岩体孤石进行防护和治理。更多还原

【Abstract】 By using theoretical formula and Rockfall process numerical simulation method,upper buckling stability was studied for dangerous rock mass boulder of Yufeng,Wenchuan,Sichuan. The results show that under natural,earthquake and storm conditions,heavy rain is the main factor of the instability of the dangerous rock mass boulder,motion characteristics of rock fall is random,and through the analysis of bounce height and movement energy of the boulder, dangerous rock mass boulder may be more effectively prevented and controlled.更多还原
