中文摘要:
      针对白石湖露天煤矿土质边坡,介绍了边坡的工程背景和现状。结合边坡地质资料,分析了爆破震动作用对边坡稳定性的影响机理,基于差分干涉SAR技术,采取实时监测的方法,利用边坡雷达对边坡沉降变形结果监测数据进行分析。结果表明土质边坡松散度较大,在爆破震动条件下,边坡稳定性较差,表面沉降变形较明显,呈现持续波动上升趋势;而在自然沉降条件下,边监测坡变形量较小,边坡监测变形相对良好。研究结果可为震动作用下的土质边坡变形特征及稳定性研究提供一定参考。
英文摘要:
      In view of the soil slope of Baishihu open-pit coal mine, the engineering background and current situation of the slope were introduced. Combined with the geological data of the slope, the influence mechanism of blasting vibration on the stability of the slope was analyzed, and the real-time monitoring method was adopted based on the differential interferometric SAR technology. The monitoring data of the slope settlement and deformation results were analyzed by using the slope radar. The results show that the soil slope has a large looseness, under the blasting vibration settlement, the stability of the slope is poor, and the surface settlement deformation is obvious, showing a continuous fluctuating upward trend. However, under the condition of natural settlement, the deformation of the side monitoring slope is small, and the monitoring deformation of the slope is relatively good. The research results can provide a certain reference for the study of the deformation characteristics and stability of soil slope under vibration.
