Abstract: This article elaborates on the role of hardness testing, and combines the comparative analysis of hardness testing and tensile strength testing to introduce the application research of hardness testing in the quality inspection of shield tunnel segment bolts in the field of subway construction. In the practical application of construction projects, hardness testing can effectively ensure the authenticity and effectiveness of the quality inspection of shield tunnel segment bolts.
Keywords: shield tunnel segments; quality inspection; hardness test
0引言
近年來(lái),很多研究成果表明,金屬的硬度與其抗拉強(qiáng)度存在正相關(guān)的關(guān)系[1-2],國(guó)家標(biāo)準(zhǔn)中也有硬度與強(qiáng)度的換算標(biāo)準(zhǔn),如GB/T 33362—2016《金屬材料硬度值的換算》。(剩余4020字)
