福州市城市桥梁裂缝普查及成因分析
|
摘要
通过对福州市在役城市桥梁的裂缝普查,对裂缝进行系统全面的分析和研究,得出桥梁最可能开裂的部位和常见的裂缝形式,总结出荷载、温度变化、收缩、施工质量等因素是导致裂缝产生的主要原因,这为提出福州市主要桥梁受灾加固方案奠定基础。
Through the investigation of all cracks on bridges being used in Fuzhou and the analysis of bridge cracks in all-round way,the usual place of cracks and the common form of them are obtained.It is discovered that the main causes leading to cracks are loading,temperature,shrinkage,construction and so on.This establishes the foundation for the scheme of disaster prevention of the main bridges in Fuzhou.
