边坡变形监测是判定边坡工程稳定性的重要手段。准确并及时进行边坡变形监测,同时采取有效防治措施以达到维护边坡稳定的目的。介绍了万花隧道边坡的基本工程概况、简单地质资料及详细的监测布置方案,收集监测数据并整理分析。分析结果表明,受隧道偏压侧土压力作用影响,偏压侧土体与桩体变形量较大;隧道埋深范围内边坡位移变形量发生突变,土体变形量在隧道顶部处最大,桩体变形量在底部处最大;在隧道顶部位置处,位移变形量与变形速率都在增大,为边坡最容易发生失稳破坏的位置。
Slope deformation monitoring is to determine the stability of slope engineering an important means. Accurate and timely slope deformation monitoring, taking effective control measures to achieve the purpose of maintaining the stability of the slope. The basic project outline of Wanhua Tunnel Slope, simple geological data and detailed monitoring arrangement are introduced. The monitoring data are collected and analyzed. The results show that due to the influence of earth pressure on the bias side of the tunnel, the deformation of soil mass and pile body on the bias side is large. The displacement of slope deformation is abrupt within the depth of tunnel, the deformation of soil mass is the largest at the top of the tunnel, The deformation of the pile body is the largest at the bottom. At the top of the tunnel, the displacement deformation and deformation rate are all increasing, which is the most prone to instability failure of the slope.
