摘要
甘肃省属于高震区,桥梁工程作为交通基础设施建设的重要组成部分,抗震性能好的桥梁应满足“小震不坏、中震可修、大震不倒”的三水准设防目标。主要立足于地震对桥梁结构的危害,结合JTG/T 2231-01—2020《公路桥梁抗震设计规范》的相关规定,探究如何有效开展桥梁工程抗震设计。
As an important part of transportation infrastructure construction,bridges with good seismic performance should meet the three-level fortification goal of not being damaged during small earthquakes,repairable during medium earthquakes and no collapsing with strong earthquake.The damage of earthquake to bridge structure is focused,and combining relative regulations of JTG/T 2231-01—2020 Code for Seismic Design of Highway Bridges,how to effectively carry out seismic design of bridge engineering is studied.
