场地地震易损性分析方法是在综合分析各种场地因素的基础上，通过建立定量化的表达方式，确立各种因素的易损性指数．以场地易损性指数的大小为依据，可以对同一地震作用下的场地破坏等级进行划分．以大连石油七厂场地为实例，进行针对性的易损性分析，阐明场地地震易损性分析的具体思路 The site vulnerability analysis method is based on the comprehensive analysis of various site factors, through the establishment of quantitative expression, establish the vulnerability index of various factors. Based on the magnitude of the site vulnerability index, the site damage classification under the same earthquake can be divided. Taking the site of Dalian No.7 Oilfield as an example, this paper analyzes the vulnerability of the site and clarifies the specific ideas of vulnerability analysis of the site
