既有海工混凝土结构保护层厚度的变异性分析

Variation analysis of cover depth of existing marine concrete structures

采用混凝土保护层厚度测试仪对海工混凝土结构进行现场检测;通过对3座既有海港码头结构的现场检测数据的统计分析,发现检测数据具有较大的离散性,但其均值与设计值相近,且保护层厚度测试值服从正态概率分布。

The cover-meter testing method is used to measure the cover depths of marine concrete structures.A statistical treatment is applied to the cover depth from field inspection for three existing marine wharves.The results show that the derivation of the testing values is very large,the mean value is very close to the design value,and the testing values of cover depths follow a normal probability distribution function.
