岩石高边坡安全监测及稳定性分析

Safety Monitoring and Stability Analysis of High Rock Slope

针对某水电站岩石高边坡的工程实际,为了有效的控制高边坡变形和准确的指导施工,在边坡布设了多套位移计和锚杆应力计,并且进行了边坡变形和应力监测。通过大量的边坡监测资料,并且结合变形、地质、开挖等因素,分析了边坡变形特征及锚杆的锚固效果,监测数据的分析主要采用回归方法进行。监测数据表明,边坡的锚固效果良好,边坡的变形得到了有效的控制。通过此岩石高边坡工程的施工监测,阐明信息化施工可以保证边坡的稳定性,正确指导施工。

Aiming at the project reality of high rock slope in a hydropower station,the authors buried multi-wrap displacement meters and anchor stress-meters and carried out slope deformation and stress monitoring in order to effectively control the high slope deformation and accurately direct the construction.The characteristic of slope deformation and the effects of anchor bar was analyzed using a lot of slope monitoring-data combined with the factors of deformation,geology and excavation in this paper.The regression method is used in the analysis.The monitoring data indicate that the slope anchor effect is good and the slope distortion is effectively controlled.It is shown that information-oriented construction can ensure the stability of slope and correctly direct construction.
