| Elementary exploring on quantization of classification standard in pile-shaft integrity inspection test by sonic wave flaw detection method |
| 摘要 |
| 就現(xiàn)行鐵路工程基樁檢測技術(shù)規(guī)程中，有關(guān)聲波透射法檢測樁身完整性分類標(biāo)準(zhǔn)不能定量的問題進(jìn)行了初步探討，采用射線法和繞射法對波經(jīng)過缺陷（空洞）處的PSD值Ki進(jìn)行了計(jì)算，結(jié)果發(fā)現(xiàn)，PSD值Ki與缺陷大小、混凝土強(qiáng)度等級(jí)、樁直徑、測點(diǎn)移動(dòng)步距有關(guān)。根據(jù)計(jì)算結(jié)果結(jié)合實(shí)踐經(jīng) |
