摘要
龙江水电站左岸缆机平台边坡高陡,在建设过程中出现局部坍塌、落石等异常现象,采用了"锚、排、挡"的综合治理措施进行加固处理,并通过多点位移计、锚索测力计等仪器进行监测。龙江水电站左岸缆机平台高边坡岩体内部变形及应力监测资料表明,边坡岩体在加固后变形趋于收敛,边坡整体稳定,但鉴于该边坡地质条件复杂且受降雨影响显著,其稳定性仍需要继续进行跟踪监测分析。
During the construction of slope works of cable crane platform on the left bank of Longjiang Hydropower Station, there were collapses and rock falling in some parts. Therefore, consolidation and treatment by means of anchoring, draining and retaining were conducted. Monitoring has been performed by the instruments of multi-point extensometer and anchor dynamometer. The monitoring data of internal deformation and stress of high slope shows that it has been stabilized thanks to the consolidation and treatment. However, further monitoring is needed since the geological condition of this area is poor and prone to rainfall damage.
