Slope safety has been well concerned by the society in recent years. Slope displacement monitoring is an important subject of slope safety and its research has been developing rapidly. In this article, we draw up a pilot slope safety automatic monitoring scheme for the project of Road No.1 in Republic of Congo, which depends on real-time displacement monitoring. This scheme uses fixed inclinometer as its main appliance and achieves wireless data transmission. During this process, we considered both local climate and the characteristics of high slopes along the road, and finished a series of work including monitoring position selection, critical slip surface prediction and finally monitoring system establishment. Our ultimate objective is to achieve real-time monitoring of slope situation, and furthermore set up the relationship among slope displacement, rainfall and time. With the derived relationship we would be able to forecast the development of slope deformation and possible danger caused by the slopes.
