摘要: 為解決超聲波檢測鋼板剪力墻空洞缺陷判斷準(zhǔn)確性的問題,在現(xiàn)有《 超聲法檢測混凝土技術(shù)規(guī)程》 ( CECS21 ∶2000)中概率法 判 斷 鋼 管 混 凝 土 缺 陷 的 基 礎(chǔ) 上,采 用 超 聲 對 測 法 通 過 KON-NM-4A 非 金 屬 超 聲 波 檢 測 儀 和50kHz 超聲波換能器,對鋼板剪力墻空洞缺陷進(jìn)行檢測. 并采用概率法、波列、波形、頻譜分析及空洞尺寸估算法從不同角度分析判斷鋼板剪力墻內(nèi)空洞缺陷的位置、尺寸,最后嘗試通過軟件 Surfer 將概率法分析的缺陷位置直觀表示. 結(jié)果表明,采用概率法可以判斷截面尺寸大于 90mm× 90mm 空洞缺陷的位置;采用波形分析法可以補充判斷截面尺寸不小于 60mm×60mm 空洞缺陷的位置;采用 Surfer 軟件可以對概率法分析結(jié)果直觀顯示.

Abstract: In order to solve the problem of the judgment accuracy of cavity defects of steel shear wall by ultrasonicdetection, based on the probability method in the existing Technical specification for inspection of concrete defects byultrasonic method(CECS 21 ∶2000) to determine the defects of concrete-filled steel tube. Ultrasonic testing method was usedto detect the cavity defects of the steel plate shear wall through the KON-NM-4A non-metal ultrasonic detector and 50kHzultrasonic transducer. Probability method, wave train, waveform, frequency spectrum analysis, and cavity size estimationmethods were used to analyze and judge the location and size of cavity defects in steel plate shear wall from different angles.Finally, the software Surfer was used to visually indicate the position of the defect analyzed by the probability method. Theresults show that the position of cavity defect with cross-section size greater than 90mm×90mm can be judged by probabilitymethod, and it can be added to judge the position of cavity defect with cross-section size not less than 60mm × 60mm bywaveform analysis method. The analysis results of the probability method could be visually displayed by software Surfer.
