摘要:
等效剪切波速是确定场地类别进而得到地表设计地震动参数的重要依据之一,不同等效方法的可靠性对比研究对工程建设的地震安全意义非常。调整典型人造场地、274个实际工程场地计算深度内的剪切波速排列顺序,讨论走时等效剪切波速(vse)以及周期等效剪切波速(vsT)二者对不同土层结构场地的灵敏性;对比采用vsevsT两种指标对收集整理的200多个场地的场地分类结果,讨论vsevsT两者在场地分类方面的一致性;放缩各场地模型各土层剪切波速,直至vse达到分类临界值,计算各场地的vsT。结果表明,计算深度内土层结构改变,vsT随之改变,而vse固定不变,即vsT相对于vse更能灵敏的反映土层结构对地表地震动参数的影响;利用vsevsT两个指标对实际工程场地的分类结果具有高度的一致性,vsT作为场地类别的划分指标具有一定的合理性和有效性;vsT的计算结果比vse偏大,当vse达到临界值时,vsT很好的呈现为正态分布,以此得到二者统计意义的转化值。
Abstract:
Equivalent shear wave velocity is one of the important parameters to determine the site category and further calculate the ground motion response spectrum. So detailed discuss the reliability of different equivalent methods has great meaning. After adjust the order of shear wave velocities of typical artificial sites and 274 actual engineering sites, we discussed the sensitivity of the travel time equivalent shear wave velocity (vse) and the period equivalent shear wave velocity (vsT) at different soil layer, respectively; and then compared their uniformity on site category with more than 200 sites. Scaling the shear wave velocities of each site model until vse reached the threshold values of site category, and calculated the vsT of that site. The results show that, vsT varied but vse keep steady when soil layer construction changed, it is mean vsT is a more sensitive parameter to reflect the influence of soil layer construction on ground motion parameters. The site classification results of two methods have high consistency when application to the actual engineering sites, so it is reasonable and effective to adopt vsT as the site classification index. The result of vsT is larger than vse, vsT shows normal distribution when vse reaches threshold values, so we can get their conversion value statistically.
