项目摘要
In 2002 a major prestressed concrete bridge in Tasmania was demolished after only 45 years in service because of fears about the corrosion of the prestressing bars. Earlier, very extensive investigations were carried out to attempt to assess the rate of its deterioration and to establish the remaining margin of safety.
The present project aims to investigate the degree of correlation between the performance assessment before and after demolition. Extensive pre-demolition documentation provided by the industry partner and detailed new assessments will give valuable research insight about the meaningfulness and reliability of investigative techniques for safety assessment. It will assist road authorities in structural assessment of bridges close to coastal marine environments.
2002年,塔斯马尼亚的一座主要的预应力混凝土桥在使用了45年之后被拆除,原因是担心预应力钢筋的腐蚀。早些时候,进行了非常广泛的调查,试图评估其恶化的速度,并确定剩余的安全范围。
