摘要
在矿山开采的过程中,必然伴随着地表水平移动、下沉或者倾斜等变形,会使穿过矿区的公路路面遭到破坏,从而引发路面隆起或地面沉陷等变形现象,这往往会带来交通安全隐患,因此需要对矿区公路进行沉降监测。传统的监测方法是利用水准仪、RTK等进行单点测量,这样只能反映公路的大体沉降趋势,不能监测公路局部情况,无法反映公路整体沉降情况。三维激光扫描技术可以通过非接触的测量方式高速获取海量高精度点云数据,相比常规监测方法更具有优势。因此本文结合实例研究了三维激光扫描技术在采动区公路沉降监测中的应用,给采动区公路沉降监测的研究提供了一种新的思路。
In the process of mining,it is inevitable to be accompanied by the horizontal movement,subsidence or inclination of the ground surface,which will destroy the road surface passing through the mining areas,thus deformation phenomena like the road surface uplift or the ground subsidence are caused and often bring traffic safety hazards,so it is necessary to monitor the settlement of the road in the mining areas.The traditional monitoring method is to measure at a single point with the level and RTK,which can only reflect the general settlement trend of the highway.While three-dimensional laser scanning technology can quickly obtain a large number of high-precision point cloud data through non-contact measurement,and it is obviously superior to the conventional monitoring methods.Therefore,this paper studies the application of three-dimensional laser scanning technology in highway settlement monitoring in the mining areas and provides a new idea for the research of highway settlement monitoring in the mining areas.
