摘要
针对贵州喀斯特地质区的抵母河特大桥建立回弹测强曲线。通过对不同强度等级的混凝土试件进行抗压与回弹试验,根据最小二乘法原理,对混凝土强度和回弹试验数据进行统计和回归分析,建立了抵母河特大桥混凝土回弹法专用测强曲线方程,为本工程混凝土强度质量检测评定提供了可靠的依据。
An exclusive rebound strength curve in allusion to Dimuhe Grand Bridge in Karst region of Guizhou Province is established. The compression tests and rebound tests of concrete specimens with various strength degrees are carried on. The statistics and regression analysis on the strength and rebound tests data of concrete are carried out based on the principle of least square method. Then an exclusive strength curve equation based on the rebound method for Dimuhe Grand Bridge is established, which provides reliable basis for the quality detection and evaluation of concrete strength.
