场地划分标准对基岩地震动参数衰减关系的影响
|
摘要
基于美国NGA强震观测数据库中描述场地的不同指标,定义了五种不同的"基岩"场地类型,得到了相应的数据集;同时采用最小二乘法回归得到了世界范围内对应不同"基岩"定义的地震动参数衰减关系,并研究了不同场地划分标准造成的基岩地震动参数衰减关系的差异。
Based on the different indices that classify the site condition in the strong-motion observation database of USA NGA,five different rock-type sites are defined altogether,and the corresponding data set are obtained.Then the ground-motion attenuation relationships corresponding to different definitions of rock site are regressed by the least square method.The difference of the attenuation relationships of rock ground-motion parameters caused by the different site classification criteria is also studied.
