近日,交通运输部颁布实施了《公路桥梁抗震设计细则》、《公路桥梁加固设计规范》和《公路桥梁加固施工技术规范》三个新的公路工程行业标准规范。《公路桥梁抗震设计细则》修订的主要内容为:一是扩大适用范围,增加非规则桥梁的抗震设计内容,对特大跨径桥梁和拱桥给出抗震设计 Recently, the Ministry of Transport promulgated and implemented three new industrial standards codes for highway engineering, including “Seismic Design for Highway and Bridge”, “Code for Reinforcement of Highway Bridges” and “Technical Code for Reinforcing Construction of Highway Bridges”. The main contents of the revised Amendments to the Code for Aseismic Design of Highway Bridges are: First, to expand the scope of application, to increase the seismic design content of irregular bridges, to provide anti-seismic design for extra-large span bridges and arch bridges
