Comparative research on impact force calculation methods for rockfalls

Calculation of rockfall impact force depends on some semi-theoretical and semi-empirical methods,whose suitability and rationality have not been fully discussed and clarified.Choosing five representative rockfal impact force calculation methods,by systematic comparative research on impact force calculation results at different impacting speed,buffer layer thickness and rockfall size,the authors found that the impacrt force calculation method recommended by codes is unreliable. Because they refle...
