摘要
针对大型地下交通枢纽车站主体结构,目前已有的结构运营安全和消防安全评价方法难以对结构安全性能做准确、全面的分析。文章依据武汉复兴路车站的勘察设计资料和相关规范,采用模糊综合评价法建立大型地下结构单点-构件-区段-整体的安全分级评价指标体系。采用多级指标对结构安全评价指标的各个因素进行评价,基于乘积标度法确定每一个评价指标的权重,根据所得到的指标对应的健康等级,对车站进行结构安全评价。结合运营期复兴路大型交通枢纽的健康监测数据评价当前结构安全状态,保障车站运营安全,降低潜在损失。
For main structure of a large underground transportation hub station,the current methods for evaluating structural operation safety and fire safety are difficult to make an accurate and comprehensive analysis of structural safety performance.So,according to the survey and design data of Wuhan Fuxing Road Station and relevant specifications,the fuzzy comprehensive evaluation method was adopted to establish the safety classification evaluation index system of single point-component-section-whole for the large underground structure.The multi-level indexes were used to evaluate various factors of structural safety evaluation indices,the weight of each evaluation index was determined based on the product scale method and the structural safety evaluation of the station was performed according to the health level corresponding to the obtained index.The current structural safety status was evaluated in combination with the health monitoring data of the large transportation hub at Fuxing Road during the operation period so as to ensure the operational safety of the station and reduce potential losses.
