【摘要】 边坡的安全与稳定是水电工程建设中的重中之重。对安全监测设备反馈的实时数据进行分析,可对边坡的运行性态做出评价。本文通过腾龙桥一级水电站左岸边坡锚杆应力计的受力分析,旨在掌握施工期间岩土体所受的应力、边坡的变形情况及岩土体锚固效果,为边坡稳定性分析提供数据支持及为边坡开挖施工提供参考信息。监测数据显示:在成活的20支锚杆应力计中有17支锚杆受力已基本达到稳定状态,其余3支也在逐步趋于稳定;锚杆最大拉应力值为130.62MPa,这表明左岸边坡岩土体受力稳定。更多还原

【Abstract】 The safety and stability of slope are very important in hydropower construction project. Based on the data analysis from the safety monitoring equipments,the slope evaluation of running state can be made. Through the anchor force analysis,the rock mass stress and deformation of slope and the rock anchoring effects can be obtained to provide data support and reference information for the slope stability analysis and slope excavation. The monitoring data shows that most of the anchor stress gauges have reached steady state. The anchor maximum stress value is 130. 62 MPa,which indicates that the rock mass of the left bank slope is in stable state.更多还原
