粉煤灰作为路堤填料的动力特性试验研究

粉煤灰用作路堤填料时，其动力特性是大家较为关注的问题。在扬州电厂粉煤灰动三轴试验的基础上，对影响粉煤灰动强度的若干影响因素进行了分析，对粉煤灰路堤在饱水条件下的抗液化性能进行了探讨。研究结果表明：振次、初始静应力水平、含水量等对粉煤灰的动强度都有显著的影响；粉煤灰路堤在饱水条件下的抗液化性能则与地震动峰值加速度、初始静应力水平等有密切关系。

Experimental research on dynamic properties of fly ash for embankment filling

Based on the triaxial tests of fly ash of Yangzhou Power Plant,some factors affecting the dynamic intensity of fly ash for embankment filling are analyzed. The capability resisting liquefaction of fly ash embankment under saturated condition is also discussed. The research results show that the vibration times, initial static stress level and water content etc. have obvious influence on the dynamic intensity of fly ash; the capability resisting liquefaction of fly ash embankment under saturated condition is related to earthquake peak acceleration and initial static stress level etc..
