［摘要］以河北省范圍內(nèi)多項(xiàng)全國或省重點(diǎn)文物保護(hù)單位為對象，選取一定數(shù)量的古城墻磚，研究了豎向壓力、含水率、不同約束條件等對其回彈測強(qiáng)的影響，建立了砌筑前后古城墻磚回彈值線性回歸公式。并通過對古城墻磚回彈測強(qiáng)的研究，闡明了回彈值和抗壓強(qiáng)度之間的相關(guān)性，建立了古城墻磚回彈測強(qiáng)的回歸模型。通過實(shí)際工程項(xiàng)目的驗(yàn)證可知，該曲線的精度較好，可用于古城墻磚的回彈測強(qiáng)。

Abstract:
Based on a number of national or provincial key cultural relics protection units in Hebei province, a number of ancient city wall bricks were selected to study the influence of the vertical pressure, moisture content and different constraint conditions on rebound value. Linear regression formula of the ancient city wall brick rebound value before and after construction was set up. Through the study of the rebound value testing technology of ancient city wall bricks, the relationship between the rebound value and compressive strength was clarified and the ancient city wall brick rebound regression model was established. Through the validation of the actual project, the curve was proved to be precise to detect the rebound value and compressive strength of ancient city wall bricks.
Keywords:
