covering layer thickness

基本解釋

The influence of abr diameter is stronger than the thickness of concrete protective covering layer.
同時鋼筋直逕對鋼筋鏽脹力的影響程度要大於混凝土保護層厚度的影響。
Therefore, to investigate the minimal thickness of covering layer of underwater tunnel is greatly engineeringly significant.
因此，對水下隧道的最小覆蓋層厚度進行研究具有較大的工程意義。
The results are as follows: First, it can reflect variation of thickness of covering layer and the duration of propagation time of the shear wave in overburden layer.
結(jié)果表明，地脈動的頻譜特性與場地覆蓋層厚度和地基土剛度的變化密切相關(guān)；
