It is meaningful for researching on monitoring and forecasting technology of slope stability to prevent landslide disasters, especially in the water system fields. Based on the mechanical principle of interaction among sliding mass, sliding bed and monitoring cable, a new type of energy absorbing cable (called Large Deformation Cable with Constant Resistance) which can have 2000mm deformation with constant pull load of 850kN is developed. The mechanical principle of relative movement between sliding mass and sliding bed is proposed, and the multi-factor monitoring is transformed into single landslide mechanical monitoring. The relationship between sliding force of slope and pretightening force of monitoring cable is set up. According to the physical model experiment of landslide, the sliding force at the potential slip surface will change continually before the landslide. When the sliding force is greater than the shear resistance at the potential slip surface, the landslide will take place, which means the variation of sliding force at the potential slip surface will be ahead of displacement on the ground of slope. Consequently, monitoring the variation of sliding force at the potential slip surface is better than that of the displacement. Based on above principle and experiment, the system of real-time remote monitoring and forecasting for landslide disasters based on the large deformation cable with constant resistance is developed, which can realize the real-time remote monitoring warning of sliding force. Several landslides have been successfully predicted.

Keywords: Large deformation cable with constant resistance, landslide forecasting, remote monitoring and forecasting system, sliding force.
