Evalution of High Slope Stability at Arch Dam abutment Based on Internal Monitoring Data
The slope which located at the cable crane platform of left bank in Longjiang hydropower plant is high and steep, its stability directly related to the water intake safety of the hydropower plant.Since the slope appeared partial collapse, rockfall and other abnormal phenomenon during the construction process, anchor-drainage-barrier combined treatments were adopted to guarantee the slope stability, while monitor devices such as multi-point displacement meters and anchor dynamometers were installed to collect necessary information.Under the guidance of the principle of dynamic design, safety monitoring and feedback analysis, information management, the design of the controlling measures is reasonable and the monitoring system layout is appropriate.Therefore, a large number of effective information is obtained and provides the basis for the post-evolution of the control effects.The inner deformation and stress monitoring data of the high rock slope shows that the deformation of the reinforced slope tends to convergence and the slope is general stable, however its stability is still needed to be tracked and monitored considering the complex geological condition and remarkable influences of the rainfall of the slope.
