Debris flow impact force measuring and calculating method and application and blocking energy dissipation pile array design method
The invention discloses a debris flow impact force measuring and calculating method and application and a blocking energy dissipation pile array design method. According to the method for measuring and calculating the vertical impact force of the landslide debris flow, the distribution of the vertical impact force of the debris flow to the impact position is measured and calculated by measuring and calculating the tangential movement speed of the landslide debris flow at the impact point. Furthermore, according to the pile array design method, the free section of the energy dissipation pile is simplified into a cantilever beam, anti-bending counterforce is generated when the cantilever beam is impacted by the debris flow, the anti-bending counterforce continuously acts as impact kinetic energy of the debris flow to dissipate the impact kinetic energy of the debris flow, and according to the motion characteristics of the landslide debris flow, parameters such as impact force acting time and distance are further deduced; the problems of energy dissipation pile monomer flexural deformation stability parameter design, energy dissipation parameter design of the blocking energy dissipation pile array and blocking energy dissipation pile array number parameter measurement and calculation are solved hierarchically. The invention further provides application of each calculation design method. According to the method, a more scientific and perfect scheme is provided for the energy dissipation design of the blocking energy dissipation pile array for coping with rolling stone and debris flow impact damage of landslide disasters.
