【摘要】：提出涵洞与路段、桥梁、隧道等构成交通系统易损性分析单元,即作为震害影响因素参与交通系统的网络连通性分析。为了建立涵洞群体易损性分析方法,通过调查统计四川汶川特大地震震后陇南公路总段部分线路所辖的样本涵洞破坏情况,总结涵洞在特定的地震地质灾害环境中易损部位和易损现象,分析致灾原因,初步确定震害因子。并结合对比研究唐山大地震中涵洞震害资料,划分样本涵洞的破坏等级,下步推导公路涵洞群体的地震易损性经验统计公式。
[Abstract]:The vulnerability analysis unit of traffic system composed of culverts, road sections, bridges and tunnels is put forward, which is the network connectivity analysis of traffic system as the influence factors of earthquake damage. In order to establish a vulnerability analysis method for culverts, the sample culvert damage of the main section of Longnan Highway after the Wenchuan earthquake in Sichuan Province was investigated. This paper summarizes the vulnerable parts and phenomena of culverts in the specific environment of seismic and geological disasters, analyzes the causes of the disasters, and preliminarily determines the seismic damage factors. Combined with the comparative study of culvert damage data in Tangshan earthquake, the damage grade of culvert samples is divided, and the empirical statistical formula of seismic vulnerability of culvert population is derived.
