| 摘 要： | 探讨了在工程场地地震安全性评价的地震反应分析模型中,江苏省盐城地区部分工程场地内深度超过100m时剪切波速仍小于500m/s的控制性深孔,采用近似估算方法弥补所缺波速值和确定地震输入界面后,进行波速值和地震输入界面位置的不确定性对工程场地地震反应的影响研究,包括地表地震动峰值加速度和反应谱特征周期等,为其他地区控制性深孔的地震输入界面位置的确定方法和影响研究提供参考。

| Abstract: | Based on parts of deep governing holes those which shear wave velocity is less than 500m/s at a depth of 100 meters in Yancheng city of Jiangsu Province, seismic response analysis models of evaluation of seismic safety for engineering sites are discussed by refilling shear wave velocity and determining earthquake input interface. Effect on the seismic response analysis by the uncertainty of shear wave velocity and earthquake input interface are developed, including the surface peak ground acceleration value and characteristic periods of response spectra. Our results can offer reference to the determination measures and effect of earthquake input interface in deep governing holes in other related regions. |
