摘要
在高陡边坡下进行爆破作业,为确保边坡及生产的安全,需对振动条件下边坡的动态稳定性有所了解。相关的研究成果已表明,FLAC 3D用于爆破荷载作用下边坡的动态响应分析是可行的。利用FLAC3D软件建立了丽江阿海电站左岸高陡边坡的三维模型,将现场实测的振动数据从边坡底部输入,分析了爆破结束后边坡体内位移场、应力场以及速度场的分布情况,从而判断该边坡在爆破荷载作用下的稳定性。
It is important to explore the dynamic influence of blasting vibration on slope for the production safety in high steep slope blasting engineering. Related researches show that the FLAC3D can be used for dynamic response analysis of the slope ,then a 3D model of Ahai power station＇s high-steep slope was built by the software FLAC3D. By inputting the measured vibration data from the slope bottom, the stress field distributions, displacement field and velocity field in the slope were analyzed, which helps to disclose the effect of blast loading on slope stability.
