摘　　要：不破坏结构而能对已建成的混凝土结构或正在施工的混凝土工程质量进行定量的评价,这是无损测试技术要实现的根本目的。通过回弹测强建立回弹值与芯样实测抗压强度之间的关系方程,并由这种关系方程来推定整个工程混凝土的抗压强度,进而达到评价混凝土内部质量的目的,避其钻芯法造成结构或构件的局部破坏,以便更全面地反映厚实混凝土的质量情况。The main purpose of no-damage test technique is to quantify the concrete qualities for projects constructed and under construction. The author establishes the correlation regression equation between the resilience value and the pressure-resistance intensity of core samples to estimate the pressure--resistance intensity of the whole concrete structure, and to evaluate the inherent quality of concrete structure. In this way, the local damage to the structures by core auger method can be avoided, and the actual quality of thick and solid concrete structure can be reflected.
