1超聲波檢測(cè)原理常用的基樁動(dòng)測(cè)方法包括低應(yīng)變反射波法、高應(yīng)變動(dòng)測(cè)法、超聲波法、動(dòng)測(cè)法等。超聲波法檢測(cè)基樁由于檢測(cè)精度高、不受樁長(zhǎng)、樁徑條件限制、測(cè)試無盲區(qū)等優(yōu)點(diǎn)，在混凝土基樁檢測(cè)中應(yīng)用越來越普及。其檢測(cè)原理是對(duì)計(jì)劃采用超聲波法檢測(cè)樁身質(zhì)量的基樁，施工時(shí)在樁身中埋入聲測(cè)管，檢測(cè)時(shí)發(fā)射換能器和接收換能器分別置于兩根管道中，由聲測(cè)管底部開始，發(fā)射探頭在某一個(gè)聲測(cè)管中邊上升邊發(fā)射高頻信號(hào)，該高頻信號(hào)穿過混凝土被另一個(gè)聲測(cè)管中同步移動(dòng)的接收換能器所探測(cè)。隨著探頭沿整個(gè)樁長(zhǎng)提升，依次測(cè)取各測(cè)點(diǎn)超聲脈沖穿過兩管道之間的混凝土，通過實(shí)測(cè)超聲波在混凝土介質(zhì)中傳播的聲時(shí)、波幅和頻率等參數(shù)的相對(duì)變化來檢測(cè)聲測(cè)管之間混凝土的缺點(diǎn)位置及影響程度，判定樁身完整性類別。混凝土是由多種材料組成的多相非勻質(zhì)體。對(duì)于正常的混凝土，聲波在其中傳播的速度是有一定范圍的，當(dāng)傳播路徑遇到混凝土有缺點(diǎn)時(shí)，如斷裂、裂縫、夾泥和密實(shí)度差等，聲波要繞過缺點(diǎn)或在傳播速度較慢的介質(zhì)中通過，聲波將發(fā)生衰減，造成傳播時(shí)間延長(zhǎng)，使．聲時(shí)增大，計(jì)算聲速降低，波幅減小，波形畸變，利用超聲波在混凝土中傳播的這些聲學(xué)參數(shù)的變化，來分析判斷樁身混凝土質(zhì)量。昆明聲測(cè)管規(guī)格，云南貿(mào)軒商貿(mào)有限公司。</p><div

聲測(cè)管連接處套管過長(zhǎng)由于鋼套管過長(zhǎng)，焊接質(zhì)量較好，密封在內(nèi)部的空氣不能排出，聲波信號(hào)要繞行很長(zhǎng)距離或穿過空氣層才能被接收到，造成聲波信號(hào)的嚴(yán)重異常，影響樁身完整性的判定。2．4
