结合汶川地震中桥梁的震害规律浅析辽安路桥梁设计的注意事项

Brief Analysis on Attention Matters of Liao'an Road Bridge Design Combined with Regulation of Bridge Seismic Damage in Wenchuan Earthquake

通过对汶川地震中桥梁震害规律的分析,总结得出桥梁震害的原因,从而指出《公路工程抗震设计规范》存在的几点缺陷,并印证了《公路桥梁抗震设计细则》主要修订内容的正确性。最后,结合辽安路的设计,简要介绍如何按照《公路桥梁抗震设计细则》进行桥梁抗震设计。

Reasons of bridge seismic damage are summarized through the analysis of regulation of bridge seismic damage in Wenchuan earthquake.Thus,the defects in Specifications for Aseismatic Design for Highway Works are indicated and correctness of main revised content in Detailed Rules for Anti-seismic Design of Highway Bridges is verified.Finally,how to perform bridge anti-seismic design is introduced according to Detailed Rules for Anti-seismic Design of Highway Bridges combined with Liao＇an design.
