Research And Case Study In Measurement Of Surface Deformation Monitoring In Landslid

Landslide monitoring is one of an important prevention and prediction of the basic work, which can understand and master the specific development and evolution of slope, which make the evaluation and prediction of the slope stability and the development, which provide reliable information and scientific basis for the protection. Surface deformation measurement techniques can directly monitor the three-dimensional landslide displacement and the displacement direction and velocity, which occupy an important position in the landslide monitoring. Because the science and reliability of the monitoring results of surface is directly related to the accuracy of results, the system of monitoring landslide surface deformation is necessary in all aspects.For these reasons, the surface of paper in the Journal of landslide monitoring data based on the literature and refer to a large number of engineering case, the system of landslide deformation characteristics and correlation of deformation monitoring, Specific results are as follows:1,Based on the evolution of the landslide and the deformation characteristics of spatial form, deformation measurement for monitoring the technical characteristics of deformation monitoring methods for the selection and arrangement of monitoring points put forward relevant measures to ensure better monitoring results reflect the trend of landslide deformation and Described with relevant projects.2,According to over landslide and landslide deformation characteristics of traction, combined with a large number of engineering examples to illustrate how to use monitoring data to analyze the type of landslide and to predict based on their spatial characteristics. On the soil slope, the deformation characteristics of rock landslide were introduced, and in accordance with their respective characteristics, were targeted monitoring points layout; destroyed by the landslide soil in different ways, the corresponding prediction method. 3,Combination of engineering practice, details of surface deformation monitoring and control network principles to determine the measuring point landslide. Of monitoring instruments to evaluate their applicability, and the deformation monitoring methods are summarized, and relevant projects are described. Monitoring data obtained can be summarized by a landslide deformation of the feedback information, combined with the related detailed engineering example.4,Taking a Landslide for example, it described in detail the surface of the slope deformation monitoring the implementation process, causes deformation of the slope analysis, and according to the slope outside the body of works conditions and effect factors of time and space effects analysis.
