摘要
对钢管混凝土系杆拱桥实施了常规检测和动、静载试验,并结合有限元建模与分析;最终对桥梁进行了安全评估,为桥梁的日常养护维修提供了依据。从荷载试验结果看,桥梁的各项检测指标符合试验规程要求,即当前尚满足设计荷载等级;但由于该桥的结构特点,针对现存的安全隐患,应立即组织维修。
The concrete filled steel tube bowstring arch bridge has been made daily detection,live & static load tests combined with finite element modeling and analysis.Related safety assessment of this bridge has been given to provide a basis for its daily maintenance.The load tests results show that every detection index of this bridge can meet with the requirements of experimental standards,which means this bridge just can satisfy the design load class at present.Therefore,aiming at the current potential safety hazard,this bridge should be repaired as soon as possible due to its structure features.
