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。制作了7组不同配合比的粉煤灰、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 resolve the problem of libration collapse, coast and project defense in engineering practicality, the research on dynamic experiment of modified geomaterials has became the important topic of rock engineering speciality.Seven groups of test sample with different proportion of powder ash and cement modified geomaterials and one group of test sample with original soil are founded, using SHPB bringing to bear dynamic load.And analyzes dynamic capability of modified geomaterials and original soil test sample.The experiment result indicates,powder ash and cement modified geomaterials possessing excellent dynamic capability.
