| 摘 要： | 基于四川及邻区8181个控制点的地震危险性分析结果,统计得出了不同风险水平下中硬场地地震动峰值加速度的比值特征.文中重点分析了大震与中震地震作用的比值(K2值)的统计特征和空间分布特征,初步分析了影响K2值的因素.本文研究结果不仅可为抗倒塌地震区划图编图原则和编图方法的确定提供重要依据,还可为不同行业、不同工程的抗震设计和验算提供参考.

| Abstract: | Based on probabilistic seismic risk analysis result of 8181 grids in Sichuan and adjacent region, we summed up the features of ratios between peak ground accelerations of different risk levels. We focused our research on the statistical and spatial distribution characteristics of the ratio (K2-value) between rare and medium seismic action and made a preliminary analysis on the factors affect K2-value. The result could provide not only a significant basement for determining criteria and methodology for compiling seismic zonation maps against collapse of structures, but also a reference to aseismic design and checking computation for different industries and engineering. |
