摘要
根据粉煤灰的特性 ,分别对原状粉煤灰和击实粉煤灰进行了动力特性试验研究 ,提出了可靠的动强度参数和动剪切模量及阻尼比参数 .在此基础上 。
According to the characters of fly ash, the dynamic characters laboratory test have been done for the undisturbed fly ash and compacted fly ash. The credible dynamic intensity parameter and dynamic modulus in shear parameter and damping ratio parameter are proposed. Based on this, the earthquake liquefaction characters have been analysed for the undisturbed fly ash and fly ash dam in different conditions.
