【摘要】：提出涵洞與路段、橋梁、隧道等構(gòu)成交通系統(tǒng)易損性分析單元,即作為震害影響因素參與交通系統(tǒng)的網(wǎng)絡(luò)連通性分析。為了建立涵洞群體易損性分析方法,通過調(diào)查統(tǒng)計四川汶川特大地震震后隴南公路總段部分線路所轄的樣本涵洞破壞情況,總結(jié)涵洞在特定的地震地質(zhì)災(zāi)害環(huán)境中易損部位和易損現(xiàn)象,分析致災(zāi)原因,初步確定震害因子。并結(jié)合對比研究唐山大地震中涵洞震害資料,劃分樣本涵洞的破壞等級,下步推導(dǎo)公路涵洞群體的地震易損性經(jīng)驗統(tǒng)計公式。
[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.
