ASSESSMENT AND REINFORCEMENTS OF THE PIERS AND GIRDER OF A HIGHSPEED RAILWAY BRIDGE AFTER FIRE
-
摘要: 某高铁桥墩及跨梁在火灾后受到一定损伤,对该区域检测分析的过程进行介绍,包括过火温度判断、碳化深度、强度检测以及用弹性波检测影响深度等。经初步评级及详细评级,对受火灾影响的柱墩及预应力梁提出修复建议。Abstract: Two piers and a girder of a high speed railway bridge were damaged to some extent after fire.It was presented the detection and analysis process of the damaged area,including judgement of fired temperature,carbonization depth,strength detection,the detection of the affected depth by elastic waves etc.It was finally proposed the repair sugestions on the damaged piers and girder after the initial and detailed evaluations.
