摘要
通过对混凝土试块物理力学参数的试验及统计分析研究,建立了拔出法与超声拔出综合法的测强曲线。结果表明,拔出法测强曲线符合规范要求,可以使用;超声拔出综合法较拔出法有更高的准确度与可靠性。
Based on the analy sis of data that have been gotten from test on numerous concrete samples, the regression formulas of pull-out method and ultrasonic-pulling out method of commercial concrete strength were obtained. The formulas satisfy the related demands and ultrasonic-pulling out formulas have better accuracy.
