摘要
贵阳市北京东路狮子山山体存在危岩较多,其中有一段危岩体裂隙明显,直观时安全隐患较大,且环境较为复杂。危岩体高度20 m。采用爆破方式处理,要对危岩体进行安全防护,以防止在爆破震动的影响下,危岩体整体下滑。首先对危岩体的稳定性进行了定量分析,然后对安全防护的强度进行了校核,以使施工能安全顺利的进行。结果显示危岩体在不受外界动载的影响下,基本稳定;设计的防护强度完全可以安全防护危岩体。
Lion rock in Beijing east road of Guiyang exists many dangerous rock.One section of rocks has significant fractures and complicated environment,the hidden danger is large.The height of dangerous rockmass is 20 m.When blasting,safety protection must be used to avoid rock gliding effected by blasting vibration.The stability of dangerous rock is analyzed quantitatively,then the strength of safety protection is checked to ensure construct safety.The analysis results show that,the dangerous rock without external dynamic load is stable,and the strength designed is enough to protect the dangerous rock.
