摘要
Due to complex environment on the slope and changeable motion trace of rockmass,landslide and rockfall’s velocity and acceleration is difficult to estimate.Through analyzing on videos data of Gongjiafang failure and man-made rockfall tests,the paper study dynamic and energy reduce problem on moving object along the Gongjiafang slope.Studies have shown that the slump-mass as a whole experienced an acceleration ~ deceleration process,and the rockfall in the whole course of the campaign experienced a number of acceleration-deceleration process,the velocity of a single rockfall is slightly larger than that of the overall landslide in and into the water velocity.In the movement from the beginning to the whole into the water,energy attenuation rate of sliding masses is about 97.2%,that of the rockfall is around 92%.The result can offer information to manage Gongjiafang potential rockfall and other impulsive wave generated by the similar landslide.
