In recent years，Chinese enterprises have contracted many pile foundation projects of port and waterway in the“One Belt and One Road”countries，but due to the lack of understanding of foreign codes，it has brought some troubles for the pile integrity tests. Taking Chinese code Technical specification for testing and inspection of port and waterway engineering foundation， American codes ASTM （D5882，D4945，D6760，D7949），and European codes （EN1997，EN1536，EN12699）as examples，the differences of pile foundation integrity tests in port and waterway engineering according to the three sets of current codes in China，America，and Europe in terms are compared，and the main results include：1）The Chinese code specifies the proportion of integrity test and divides the integrity of pile into four levels. 2） The American codes include thermal analysis，which enriches the testing method. 3） The American codes are only specified how the tests are to be carried out，but generally are not specified how the test results are to be used. 4） The European codes only provide the method for integrity testing without specific provisions，and the use is generally according to the local national requirements.
