（重慶市建筑科學研究院 630015）[提要] 原位軸壓法是現(xiàn)場直接測定墻體承載力的一種微破損檢測技術(shù)。測得的砌體抗壓強度能綜合反映磚、砂漿和砌體砌筑質(zhì)量的影響。本文主要是對測試時的各種影響因素進行了分析。通過大量的對比試驗得出了與標準砌體之間強度換算系數(shù)的關(guān)系、適用范圍及工程應用情況。

The compression strength of the brick laying, so determined, show its complex influences by the bricks, mortar and the quality of laying. This paper mainly analyses various influential factors from the measurements. A large amount of contrast tests gives the strength conversion coefficient in relation to the standar brick layings and its applicable extent. Finally its applications in practical engineering situations are illustrated.
