岩崩滑坡地质灾害变形监测工作贯穿防治工程实施前、中、后各阶段,是反馈防治施工设计、指导施工与检验工程防治效果的重要手段。以长江三峡库区链子崖危岩体T8~T12缝险段变形监测为例,简述链子崖危岩体监测系统,变形监测成果表明危岩体变形监测系统在防治工程中发挥了十分重要的作用:链子崖T8~T12缝险段危岩体呈现不均匀蠕动变形,实施治理非常必要;治理工程实施中底部煤层采空区承重阻滑工程施工扰动了危岩体,加速危岩体的变形,为及时调整施工顺序、控制施工进度提供了依据;治理工程结束后危岩体变形在误差范围内,渐趋稳定,表明治理效果明显。
Rockmass landslide deformation monitoring of geological disasters throughout the prevention and control project implementation before, during and after each stage, is the construction of the feedback control design, construction and testing guide the effectiveness of prevention and control of an important means. Taking the deformation monitoring of T8 ~ T12 dangerous sections of the Zhiziya dangerous rock mass in the Three Gorges Reservoir area as an example, the monitoring system of the Zhiziya dangerous rock mass is briefly described. The deformation monitoring results show that the monitoring system of the rock mass deformation plays a very important role in the prevention and control project Role: chain cliff T8 ~ T12 dangerous section of dangerous rock showing uneven creep deformation, the implementation of governance is necessary; governance project in the bottom of the coal seam mined-out area of the load-bearing blockade of dangerous rock mass disturbance, accelerate the deformation of dangerous rock mass , Which provided the basis for timely adjusting the construction sequence and controlling the progress of construction. After the completion of the control project, the deformation of the rock mass was within the error range and became stable, indicating that the treatment effect was obvious.
