摘要
通过对饱和状态下不同级配粗颗粒坝料的动力特性试验成果的研究分析,得出了动强度、孔隙水压力、动模量及阻尼比在振动荷载作用下的变化曲线及规律,对这些关系曲线进行了归一化处理,所得结果为设计单位进行动力分析、评价提供了依据.
Through an analysis of the test results of dynamic characteristics of rock filling materials in saturation status by different gradation, the changing curves and rules of the dynamic intensity,pore water pressure,shearing module and damping ratio by dynamic load can be obtained and the treatment of whole normalization of the characteristic curves is also used .These parameters of material characteristics are important data for the dynamic analysis and seismic safety evaluation.
