摘　　要：为实现对地质灾害易发区地表沉降与地下沉降的同步、实时、自动监测,研发了基于北斗系统的地质体地表与地下一体化沉降监测新方法。该方法融合了北斗系统、静力水准仪、分层沉降标等沉降监测技术,监测原理如下:在稳定区域设置北斗基准点,在监测区域设置工作基点与监测点;工作基点处的北斗卫星接收机与静力水准仪安装至同一桩上,北斗卫星接收机观测工作基点处静力水准仪的绝对沉降;监测点处的静力水准仪与分层沉降标同轴连接,分层沉降标将深层沉降引至地面由静力水准仪观测;北斗系统与静力水准系统同步采集数据,数据经时间同步后分别得到工作基点和监测点的绝对沉降量。该新方法成功解决了大面积沉降监测中面临的非稳定工作基点校测问题,实现了对地质体地表与地下沉降的远程和实时监测。In order to achieve synchronous,real-time,and automatic monitoring of surface and sub-surface settlement in geological disasterprone areas,a new method for integrated subsidence monitoring of geological bodies based on the BeiDou navigation satellite system(BDS) is developed.This method integrates BDS,hydrostatic leveling system(HLS),layered settlement marker and other settlement monitoring technologies.The monitoring principle is as follows:The datum mark of BDS was set in the stable area,and the working datum mark and monitoring points are set in the monitoring area;The BDS receiver and the hydrostatic leveling instrument at the working datum mark are installed on the same pile,and the absolute settlement of the HLS at the working datum mark are observed by the BDS receiver;The hydrostatic leveling instrument at the monitoring point is coaxial connected with the layered settlement mark,which leads the deep settlement to the ground for observation by the hydrostatic leveling instrument;The BDS and the HLS collect data synchronously,and after time synchronization,the absolute settlement of the working datum mark and monitoring mark are obtained.This new method successfully solves the problem of calibration and correction of unstable working points in large-scale settlement monitoring,and achieves remote and real-time monitoring of surface and sub-surface settlement of geological bodies.
