软土对基岩峰值加速度的放大作用
|
摘要
以美国西部地震观测数据资料为基础,分别建立了基岩和深冲积层场地的峰值加速度衰减规律,探讨了深冲积层对基岩峰值加速度的放大作用.结果表明,美国2003版NEHRP规范对D类和E类场地的放大作用可能明显高估.
Based on the earthquake acceleration records at deep alluvium sites and rock sites in the Western United States,the attenuation laws of peak ground acceleration at deep alluvium sites and rock sites are obtained respectively,and amplification effects of deep alluvium sites are discussed.The results show that the amplification effects for Site Class D and E are overestimated in the 2003 NEHRP.
