【摘要】:文章在分析總結(jié)不同條件下公路隧道的實(shí)際震害程度及其危害的基礎(chǔ)上,參考建筑、橋梁、軌道交通、鐵路等其它領(lǐng)域抗震設(shè)防目標(biāo),綜合考慮我國目前的經(jīng)濟(jì)、技術(shù)狀況,提出了公路隧道基于其性能的抗震設(shè)防目標(biāo)與標(biāo)準(zhǔn)并與現(xiàn)行規(guī)范進(jìn)行了對(duì)比。結(jié)果表明,本文采用"兩水平設(shè)防、兩階段設(shè)計(jì)"的抗震設(shè)計(jì)方法,對(duì)E2地震作用下的塑性抗震設(shè)計(jì)作了明確規(guī)定,因此,對(duì)于沉管隧道、盾構(gòu)隧道以及明挖隧道十分重要,彌補(bǔ)了現(xiàn)行規(guī)范的不足。
[Abstract]:On the basis of analyzing and summarizing the actual earthquake damage degree and its harm of highway tunnel under different conditions, the paper refers to the seismic fortification targets in other fields, such as buildings, bridges, rail transit, railway and so on, and synthetically considers the present economic and technical situation of our country. The seismic fortification target and standard of highway tunnel based on its performance are put forward and compared with the current code. The results show that the plastic seismic design under the action of E2 earthquake is clearly defined by the seismic design method of "two-level fortification, two-stage design". Therefore, it is very important for immersed tube tunnel, shield tunnel and open excavation tunnel. It makes up for the deficiency of the current norms.
