摘要
分析对大型结构损伤识别产生影响的环境因素及其影响机理,以海洋平台及其所处海洋环境为例,定量分析结构在温度、湿度、附着海洋生物、附连水质量和潮汐等因素改变的情况下结构模态参数的变化。
The environmental factors and the mechanism influencing the damage detection of large engineering structures were analysed.Taking the offshore platform and its ocean environment for example,the influence of temperature,humidity,adhesion of marine organisms,added hydrodynamic mass and tide on structural modal properties was analysed quantitatively.
