| 摘 要： | 地震易损性分析是进行场地抗震性能划分的一种有效方法。根据沈阳市浑南新区的地震、地质和地貌特点 ,选取场地地基土、断层、地表地震动参数、地下水埋深和第四系厚度作为场地地震易损性分析的因素 ,并采用灰色统计方法对专家意见进行分析以确定易损性指数系数。计算结果表明 ,浑南新区的大部分地区属于抗震有利地段 ,占总面积的 81 6 8% ,抗震不利地段只占 1 8 32 %。

| Abstract: | Vulnerability analysis is a valid method used in the division of site earthquake resistance sections According to the features of seismology,geology and geomorphology of the area of the Hunnan new district,Shenyang city,5 factors such as site foundation layers,faults,surface ground motion parameter,depth of underground water and Quaternary thickness are chosen to calculate the vulnerability index The grey method statistics is applied to get the index coefficient upon experts opinios The result shows that most of the area of the Hunnan district are advantageous sections of earthquake resistance,the percentage is 81 68%,and others are disadvantageous sections of earthquake resistance,the percentage is 18 32% |

| Keywords: | Vulnerability analysis Foundation layers Index Coefficient Advantageous sections of earthquake resistance |
