英文摘要	The impact force on retaining structure,which is caused by granular flow comprised of dry particles originated from shallow landslide failure,still lacks systematic studies.In order to support the potential design requirement of structure used to resist this kind of impact,a series of dry granular impact experiments are conducted on one rigid barrier model.According to parametric analysis results,one nonlinear regression model is proposed to correlate total normal impact force at critical time(Fcr)with its influential parameters.Further,we complete a systematic statistics analysis and obtain a subsequent optimum regression equation based on the proposed model.According to experience and dimension balance,the equation is modified and finally transformed into one non-dimensional equation,which shows good agreement between predicted and observed results.
