摘　　要：通过对比我国现行关于钻芯法检测混凝土强度的基本规程标准后,从桥梁工程的具体特点出发,首次提出采用钻芯法检测桥梁实体混凝土强度时,按预应力和非预应力混凝土构件分类,根据两类构件的特点,按不同的方法进行混凝土强度评定。By comparing the existing on the basic specification and standard of testing concrete strength with drilled core,starting from the specific characteristics of bridge engineering,first proposed when applying core drilling method of testing bridge concrete strength,disaggregated by prestressed and non-prestressed concrete members,according to the characteristics of the two types of components,concrete strength evaluation by different methods.
