Experimental study on dynamic intensity and pore water pressure development of fly ash mixed with loess

According to the dynamic tests on fly ash samples mixed with different amounts of loess by the dynamic torsional shear instrument,the dynamic intensity and development of pore water pressure had been analyzed.Firstly,the dynamic intensity of fly ash decreased with the increasing of loess added to fly ash,and the more loess added,the less dynamic shear stress and vibration time until failure.Secondly,the cohesion of fly ash raised with the increasing of loess amount,but the frictional angle showe...
