层状岩质高边坡稳定监测技术

Monitoring Technology to Stability of Layered Rocky High Side Slope

以江阴大桥南塔区层状岩质高边坡及地基基础安全监测为例 ,阐述其安全监测设计的原则、监测网点的合理布置、破碎边坡岩体中测斜孔埋设技术以及边坡稳定安全监控模型的建立。提出基于外部变形观测成果的边坡稳定性判别准则 ,基于剪切位移。

Based on the example of monitoring to the stability of the layered rocky high slope, base and foundation of the south tower of Jiangyin Bridge, the discipline of monitoring mesh design to its stability, the rational arrangement of monitoring spots, the embedding technology of hole with clinometer in fragmentary rock mass in high slope and the establishment of the monitoring and predictive model to the stability of high slope are elucidated. The discriminating discipline for the high slope stability based on the monitoring deformation result, and the quantitative evaluation method based on shear slip, axial force and horizontal pushing force for the stability of high slope are suggested in the article.
