    Abstract：Through the analysis of the problems existing in the current structural detection using the core drilling method to test the strength of concrete，according to a large number of engineering practical experience and the concrete strength test values of different parts in the relevant engineering examples，we concluded that corresponding effect will be obtained when drilling core in different parts of the concrete member and the concrete strength value obtained by drilling in which part of the core sample is the most objective and accurate，which providing a more accurate distribution principle and core sampling method for the party requiring core sampling and the actual core sampling operator.
