摘　　要：为解决工程实际中遇到的振动塌方、滑坡及工程防护问题,改性岩土材料动力学性能研究成为岩土工程专业重要研究课题。制作7组不同配比的粉煤灰、水泥改性岩土和1组原状土试件,利用分离式霍普金森杆SHPB施加动荷载,分析改性岩土和原状土试件的动力学性能。试验结果表明,粉煤灰、水泥改性岩土材料具有优良的动力学性能。In order to solve the vibration collapse, landslide and engineering protection problem of actual engineering, dynamic performance research on modified rock soil material becomes the important research topic of rock soil engineering profession. Seven sets samples of different ratio fly ash, modified rock soil and one set of original shape soil were made. The SHPB equipment was used to apply dynamic load. Dynamic performance of modified rock soil and original shape soil was analysed. Results of experiment indicate that the rock soil materials modified by fly ash and cement have good dynamic performance.
