摘要
本文首先结合东、西塔场地实际情况,对其场地类别、地基震害进行评判;然后采用综合概率法对工程场地进行地震危险性分析;最后结合试验测定的场地岩土力学性能,采用一维等效线性化波动法计算地震动土层反应,得到供结构地震反应分析的场地地震动参数。
Based on the actual situations of sites in East and West Towers, the site classes and foundation shock hazards were first evaluated. Then probability analysis and deterministic parsing were employed to conduct the seismic risk analysis of the project sites. Finally, seismic responses of the soil layer were calculated by means of one - dimensional equivalent linearized fluctuation as well as the test - determined site geotechnical mechanical performances, in order to attain the site seismic parameter for structure earthquake response analysis.
