Discontinuous Deformation Analysis and Its Application to the Deformation Forecast of Dangerous Lianziya Cliff

Aimed at the problem of character of deformation and forecasting of discontinuous blocks in geological disaster,the theory and application research has been systemically done in the side of the value simulation and forecasting on geological disaster with the discontinuous deformation analysis method.Particular analysis of geological structure of Lianziya is made.Deformation and control simulation have been made on two section planes of dangerous precipitous cliff,and a series of displacement field pictures are obtained.From the result,we can affirm that the deformation of dangerous precipitous Lianziya cliff has the direct relationship with the structure of the mine-out area and the T11 segment,and the simulation results are basically according to the reality.
