Test study on dynamic characteristics of flyash used as drainage blankets of dams

BAI Bing, ZHOU Jian (Department of Geotechnical Engineering, Tongji University, Shanghai 200092, China)  
For the study of possibility of using flyash as the drainage blanket of dams, based on laboratory test results, the liquefaction strength of several sizes of flyash are analyzed, and furthermore, the sample that can be satisfied with liquefaction strength is chosen firstly. Then, based on a large number of static and dynamic laboratory test results, the calculation formulation on dynamic modules of shear deformation, damping ratio, dynamic pore water pressure, dynamic residual deformation are proposed, the parameters of these formulations are also given. Combining test results with dynamic analysis, the study shows that it is feasible to use flyash as the drainage blanket of dams.
