某坝区溢洪道中段外侧边坡采空区上覆岩体变形特征研究

Study of Roof Deformed Features on Top of the Mined Area Within Slope Outside Intermediate Section of Spillway in Some Dam

深入调查与研究了西南某水电站坝区溢洪道中段外侧边坡煤层采空区的分布特征,根据最终变形特征预测了地表移动变形的大小及其对该段外侧边坡整体稳定性的影响,其研究结果对边坡稳定性的评价具有直接的指导意义,为类似的研究提供参考和借鉴。

Based on deeply investigating and studying on distribution of the mined area and the deformed failure pattern of the roof within the coal layer of the slope outside the spillway in the hydroelectric power station in the southwest,the final deformed features of the each point are analyzed within the range of influence.The analytical results may predict the size of the deformation and the influence of the whole stability of the slope.The study has direct instructional significance to the estimate of the slope stability,this provides reference or use for the similar study.
