During the construction and operation period of highway cut slope, to evaluate the stability of the slope, it is of great necessity to monitor the responses of the slope and its reinforced structures. Compared with the traditional manual monitoring methods of slope, remote monitoring has become the development trend to obtain a timely feedback of potential hazards. This paper presents a case of highway cut slope based on remote monitoring of axial force of anchor and displacement, and the stability of the slope was evaluated. Reinforcement meters and deep displacement sensors were respectively used to monitor the axial forces of anchors and relative displacements of the slope in the In-situ test, and a network cloud platform was used to remotely manage the monitoring data. The results indicate that the axial forces of anchors varies slowly with the increasing of monitoring time within a limited range under the seasonal temperature change, and the displacements tends to be stable except in the winter, indicating the slope is stable and the monitoring is effective. For a highway cut slope with a long length, to remote monitoring the slope with an economical and effective way, it is suggested to install a small number of sensors on the sensitive positions.
