罕遇地震隧道动力学洞口段二衬防垮塌抗震配筋技术
|
摘要
为改变隧道洞口段抗震"大震偏弱"的现状,引入了二衬防垮塌单层配筋抗震技术,与传统的双层配筋抗震技术相配合,共同进行隧道动力学洞口段的抗震设防设计。根据公路和铁路隧道现行抗震规范规定,提出了隧道动力学洞口段二衬防垮塌抗震配筋准则,并利用有限差分数值模拟技术研究了防垮塌抗震配筋适用范围,研究结果表明:设防烈度7度情况下,洞口浅埋段采用单层配筋抗震技术,洞口影响过渡段不需采取抗震设防措施;设防烈度8度情况下,洞口浅埋段采用双层配筋抗震技术,洞口影响过渡段采用单层配筋抗震技术;设防烈度9度况下,洞口浅埋段和洞口影响过渡段均采用双层配筋抗震技术进行抗震设防。研究成果对隧道动力学洞口段抗震技术的发展具有重要的意义。
In order to improve weaker aseismic behavior of a tunnel structure's fault rupture zone under large earthquakes,the monolayer reinforcement aseismic technology for the second liner collapse control was proposed cooperating with the traditional double reinforcement aseismatic technology. The aseismic design of a tunnel dynamic portal section was performed. According to the regulations of highway and railway tunnel current aseismic code,the rules of tunnel portal section second liner collapse control aseismic reinforcement were presented,and the finite difference numerical simulation technology was used to study the application scope of collapse prevention aseismic reinforcement. The results showed that the monolayer reinforcement aseismic technology is used for the tunnel portal shallow buried section,the tunnel portal effect transition section needs not to take the aseismic fortification measures under 7 degree earthquake intensity; the double-layer reinforcement aseismatic technology is used for the tunnel portal shallow buried section,and the monolayer reinforcement aseismatic technology is taken on the tunnel portal effect transition section under 8 degree earthquake intensity; the double-layer reinforcement aseismatic technology is used for the tunnel portal shallow buried section and the tunnel portal effect transition section under 9 degree earthquake intensity. These results were significant for the development of dynamic portal section aseismatic technology.
