Development and Application of Collapse Rockfall Motion Analysis and Passive Control Auxiliary Design Software
There are certain problems for avalanche rockfall disaster motion sub-simulation analysis software at home and abroad.Combined with the current situation of slope rockfall disaster,based on the rockfall model test,the impact of rockfall quality,bouncing height,falling speed and other factors on the destructive force of the rockfall disaster is systematically analyzed,and the trajectory of the rockfall motion is determined.The collapse rockfall motion analysis and passive prevention and control of the auxiliary design software(Crockfall)are further developed and it's applied in the mouse fault collapse disaster prevention and control design.The results show that:by setting the values of normal recovery coefficient,tangential recovery coefficient,rolling friction coefficient,offset ratio and other parameters,we can simulate the trajectory of falling rocks.Crockfall can realize three-dimensional auxiliary design and analysis on the results of two-dimensional simulation,and realize the large-scale and repeatable random movement of falling rocks,the selection of different types of passive prevention and control systems such as rock barriers and nets,and the optimization of the three-dimensional layout of the longitudinal and transverse directions.The rat fault collapse falling rock movement as a whole was free fall-collision bouncing-downhill rolling-secondary collision-downhill rolling mode,falling rocks mainly stay piled up in the 100-200,400 m later position,in the 152 m position at the maximum energy,the greatest destructive.
