摘要
结合河北地区古建筑维修项目,抽取一定数量的与普通粘土砖尺寸相当的小规格古建筑墙砖,开展了小规格古建筑墙砖回弹值和抗压强度的相关性、回归分析,建立了其回弹测强回归模型。并对所建立的大规格城砖及小规格墙砖测强曲线进行了对比分析,得到了古建筑墙砖的统一回弹测强曲线,促进了河北地区回弹法检测古建筑墙砖的规范化、标准化。通过实际工程项目的验证,统一回弹测强曲线的精度较好。
Combined with the ancient building maintenance project in Hebei area,a certain number of small size ancient building wall bricks corresponding to the size of ordinary clay brick were extracted,and the correlation and regression analysis of the elastic value and compressive strength of small size ancient building wall bricks was carried out.The strength measuring curve of large and small size wall brick was compared and analyzed,and the uniform rebound strength measuring curve of ancient building wall brick was obtained,which promoted the standardization and standardization of testing ancient building wall brick in Hebei area.Through the verification of the actual project,the accuracy of the unified rebound strength measurement curve is better.
