对大连石油七厂的场地地震易损性分析
|
摘要
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
Earthquake is a heavy natural disaster,th e damage level depends on not only magnitude,epicentre distance,vibration featur es of earthquake wave,but also the conditions in site.The analysis of earthquake easy damage in site is to determine the easy damage index of every factors b y eatablishing a formula,and the easy damage index in site is obtained.Accordi ng to the easy damage index in site,the division of damage levels in site of t he same earthquake can be gotten.We take the site of Dalian petroleum factory No .7 as an example to analyse the easy damage index,and also to expound the concrete thinking of earthquake easy damage analysis in site.
