高速公路下伏采空区变形监测网设计

Design of Deformation Monitoring Network in Mined-out Area under Highway

高速公路采空区衍演地质灾害。为了确切反映地表残余移动与变形程度和趋势,需对采空区地表进行布点监测。分析高速公路下伏采空区复杂地质条件及其与路基的空间位置关系,确定地表监测的布网原则、监测内容、监测范围、监测频率、监测方法,以及测点的布设和数据处理与分析模型,从而更好地实现信息化施工。

Mined-out area under highway can lead to geological disasters. In order to reflect the degree and trends of movement and deformation of surface residue, some points should be arranged on the surface for monitoring. Through analyzing the complex geological conditions of mined-out area under highway and the spatial relationship with the subgrade,some issues including the principles of monitoring distribution, the monitoring content, the monitoring scope, monitoring frequency, monitoring method for surface monitoring, and the layout of monitoring points and the model of data processing and analysis as well are determined,for better realizing the construction of informatization.
