［摘要］通過6組燒結(jié)多孔磚標(biāo)準(zhǔn)砌體試件中的回彈對(duì)比試驗(yàn)，研究了多孔磚在不同約束條件和豎向壓力下的回彈值的影響因素。通過對(duì)試驗(yàn)數(shù)據(jù)進(jìn)行對(duì)比研究和回歸分析，提出了回彈法檢測砌體中燒結(jié)多孔磚抗壓強(qiáng)度的統(tǒng)一公式，驗(yàn)證性試驗(yàn)的結(jié)果顯示該公式檢測精度較高，可為相關(guān)標(biāo)準(zhǔn)、規(guī)范的修訂提供依據(jù)。

Abstract: Based on the test of 6 standard masonry specimens, the influence of vertical load and constraints on the rebound value of the testing fired perforated bricks is analyzed. Based on the comparison of the experimental data and the mathematical statistics method, a general formula of strength calculation for fired perforated brick in existing masonry is established to provide the basis for revision of relevant standards, and experimental results show that the accuracy of the formula of strength calculation is high.

Keywords: rebound method；fired perforated brick；general formula of strength calculation
