基于性能的公路隧道抗震设防标准研究
发布时间：2018-11-15 19:17
【摘要】：文章在分析总结不同条件下公路隧道的实际震害程度及其危害的基础上,参考建筑、桥梁、轨道交通、铁路等其它领域抗震设防目标,综合考虑我国目前的经济、技术状况,提出了公路隧道基于其性能的抗震设防目标与标准并与现行规范进行了对比。结果表明,本文采用"两水平设防、两阶段设计"的抗震设计方法,对E2地震作用下的塑性抗震设计作了明确规定,因此,对于沉管隧道、盾构隧道以及明挖隧道十分重要,弥补了现行规范的不足。
[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.
