Control Design for the large-scale landslide and its operation effect assessment
In order to effectively grasp the design concept of prevention and control measures for large-scale landslides and reasonably assess their operational effects,this article takes the large-scale landslides in mining areas as the engineering background,and combines the basic characteristics of landslides to carry out the design and calculation of prevention and control measures;Based on the deformation monitoring data during the operation process,the operation effect is assessed through deformation prediction.The analysis results indicate that the deformation characteristics of landslides are relatively significant,and they are unstable under rainfall and earthquake conditions,being of a great risk of instability.In addition,considering the on-site conditions of landslides,the landslide prevention and control measures are designed as"anti slip piles+slope arrangement+drainage ditches".After calculation,it is found that all kinds of prevention and control measures are reasonable and meet the calculation and regulatory requirements.In the process of evaluating the operational effectiveness of prevention and control measures,the existing deformation values range from 20.08 to 26.15mm,with relatively small deformation amounts and all less than the designed deformation control value of 50mm,indicating that the prevention and control measures have good prevention and control effects at this stage;Through deformation prediction,it is concluded that the deformation of the 28-31 period will still increase further,but the rate of increase will significantly decrease,indicating that its deformation tends to stabilize,and the prevention and control measures also have good prevention and control effects at the later stage.Through research,the effectiveness of this landslide prevention and control measure has been fully verified,gathering experience for similar projects.
