| 摘 要： | 通过对汶川MS8.0地震强震记录资料的计算分析,给出一个与地震诱发滑坡关系比较密切的地震动加速度参数--最大临界加速度.分析表明,最大临界加速度与地震滑坡的相关性高于峰值加速度,而且可以消除峰值加速度作为判据使用时存在的问题.利用汶川地震强震资料建立了该参数在震区的衰减关系,由衰减关系得到的地震滑坡影响区域与汶川地震滑...

| Abstract: | By analyzing strong ground motion records obtained from the 2008 Wenchuan MS8.0 earthquake,a ground motion acceleration parameter,named Maximum Critical Acceleration(MCA),is given in this paper.Analyzed result shows that the parameter MCA is more relevant to earthquake-induced landslide than PGA,and by using it we may solve the problems encountered in using PGA criterion to judge whether landslide can be triggered during earthquake.The MCA attenuation relation is built based on the data from the Wenchuan ea... |
