摘　　要：基于标准贯入试验实测击数判别黏性土状态的方法,采用旧的判别标准,在一定程度上影响了岩土工程勘察的准确性。通过对以往广州及少量周边地区实际工程的岩土工程勘察分析,研究了该方法对实际岩土工程勘察的影响,提出了采用该方法时,宜采用新的判别标准。The discrimination method of clay soil state is based on the SPT blow count.The old standard of this discrimination method affects the accuracy of geotechnical engineering investigation to a certain extent.Through the analysis of geotechnical engineering investigation examples of practical engineering in Guangzhou and a small amount of surrounding areas,the influence of this discrimination method on practical geotechnical engineering investigation was studied.The new standard that should be adopted when using this discrimination method was further proposed.
