谈隧道工程抗震概念设计

Discuss on Seismic Conceptual Design of Tunnel Engineering

把在建筑结构中应用较为广泛的抗震概念设计引入到隧道抗震设计中,分析了隧道抗震概念设计的4个主要内容:场地选择、合理受力原则、构造措施及空间作用原则。最后得出隧道抗震概念设计能较好地指导隧道抗震设计,但设计理念与理论基础还需要充实。另外,高素质的设计人员也是隧道抗震概念设计中不可或缺的因素之一。

The authors put the seismic conceptual design which widely used in building structure into tunnel. Analyzed four main contents of seismic conceptual design in the mountain tunnel： site selection, proper weighted principle, constitution methods and space action principle. A conclusion is gained that seismic conceptual design is effective in guiding tunnel seismic design .Moreover, theoretical basis and design skills of conceptual design need to be packed, skilled designers are also one of the most important factors on seismic conceptual design of tunnel.
