Abstract: A slope located in the west of Zhenjiang Martyrs Cemetery is studied. An efficient and energy-saving slope monitoring device system is established based on the real-time monitoring system of the GNSS technology. The system mainly aims at displacement and rainfall monitoring. The rainfall is measured by means of the tipping bucket rain gauge. Using the GPS equipments distributed around the slope, the real-time on-line automatic monitoring system works well. Based on the Microsoft Visual C++ network technology and SQL Server 2005 database, a remote warning and forecast system for geological disasters of the slope in Zhenjiang Martyrs Cemetery is developed so as to realize the real-time remote receiving and saving of the monitoring data. It can help the administrative departments know the monitoring results in time and supports them to make wise decisions. The system sets up a rainfall warning model and integrates several time forecast models to establish the slope deformation prediction model database, all of which provide a powerful guarantee of the reliability of predictions. According to the monitored data, the slope is still in a safe state.
