在(zai)檢(jian)(jian)(jian)測(ce)(ce)(ce)貝雷(lei)(lei)橋(qiao)的(de)時(shi)候(hou)，不僅要(yao)檢(jian)(jian)(jian)測(ce)(ce)(ce)其本身(shen)，還需要(yao)檢(jian)(jian)(jian)測(ce)(ce)(ce)到檢(jian)(jian)(jian)測(ce)(ce)(ce)架。檢(jian)(jian)(jian)測(ce)(ce)(ce)架是用于檢(jian)(jian)(jian)測(ce)(ce)(ce)貝雷(lei)(lei)片(pian)(pian)剛(gang)度和(he)強(qiang)度的(de)實驗(yan)臺，所以(yi)要(yao)求(qiu)在(zai)貝雷(lei)(lei)片(pian)(pian)承受超過屈(qu)服應力(li)的(de)外(wai)(wai)載(zai)(zai)荷時(shi)，檢(jian)(jian)(jian)測(ce)(ce)(ce)架的(de)剛(gang)度和(he)強(qiang)度都(dou)能夠滿足測(ce)(ce)(ce)量要(yao)求(qiu)。因(yin)此，有必要(yao)求(qiu)得檢(jian)(jian)(jian)測(ce)(ce)(ce)架的(de)極(ji)限(xian)載(zai)(zai)荷。由上面(mian)的(de)有限(xian)元分析結果可(ke)(ke)以(yi)看出，貝雷(lei)(lei)橋(qiao)租賃，在(zai)外(wai)(wai)載(zai)(zai)荷為750kN的(de)壓力(li)下(xia)，檢(jian)(jian)(jian)測(ce)(ce)(ce)架的(de)強(qiang)度和(he)剛(gang)度都(dou)足夠滿足工程要(yao)求(qiu)。為了(le)求(qiu)得檢(jian)(jian)(jian)測(ce)(ce)(ce)架的(de)極(ji)限(xian)載(zai)(zai)荷，可(ke)(ke)以(yi)采取逼近(jin)原則(ze)，逐級增加外(wai)(wai)載(zai)(zai)荷，直到其強(qiang)度接近(jin)屈(qu)服極(ji)限(xian)。
