摘要

城市埋地燃气管网服务区域往往覆盖整个城市及其周边县城,是重要的城市生命线系统工程之一,关系着城镇居民及工业用户的用气质量。文中借鉴建筑物的震害指数取法,提出根据管道在某一地震动强度下的震害特点,并结合管道的泄露情况、修复情况及管网压力的压力变化情况来确定管道的易损性指数,采用三角模糊数定量刻画埋地燃气管道易损性等级的模糊子集,计算出各条燃气管道的欧几里得贴近度,最后采用择近原则完成管道的模糊综合评价。
The service area of Urban buried gas pipeline often covers the entire city and its surrounding,it is important to one of urban lifeline systems engineering.It affects gas quality of urban residents and industrial users.In this paper,the adapting way of the building damage index is referenced,and the adapting way of vulnerability index is proposed according to damage feature of gas pipeline post-earthquake,the situation of leakage and repair.Triangular fuzzy numbers is used to calculate the fuzzy subset of vulnerability grade of the urban buried gas pipeline.Then the Euclidean proximity of gas pipeline is calculated.Finally,the fuzzy comprehensive evaluation of buried gas pipeline is completed according to optional close principle.
