西北黄土地区河谷城市地震动参数小区划研究——以兰州为例
|
摘要
以兰州为例研究了中国西北黄土地区河谷城市的地震动参数小区划特征,论证了选择输入地震动的重要性以及地震动参数分区和当地场地特征、土层分类以及地貌分区的关系。根据兰州市区的场地条件和大量的计算结果将市区划分为三个小区,给出了各小区的设计地震动参数,编制出设计地震动参数小区划图。
Taking Lanzhou city as an example,the characteristics of groung motion parameter microzoning in cities which are located in the yellow river valley in northweastern China are studied.The importance of input data for calculating the parameter during strong earthquakes is demonstrated,the relationships between the ground motion parameter microzoning and the local cite conditions,the essences of soil layers,the geomorphological condition are analysed.According to the site conditions and calculating results the urban part of Lanzhou city is divided into 3 regions,and the parameters of each region for aseismic design are also illustrated.
