| 中文摘要: |
| 近年来，我国的企业在“一带一路”沿线国家承揽了较多水运工程桩基项目，但因对国外规范了解不够深入，给桩基完整性试验检测的开展带来很大困扰。以中国《水运工程地基基础试验检测技术规程》和美国ASTM（D5882、D4945、D6760、D7949）、欧洲标准（EN1997、EN1536、EN12699）为例，详细比较中国、美国、欧洲3套现行规范在水运工程桩基完整性试验检测中部分条款之差异，主要结果有：1）中国规范规定了完整性试验检测的比例并将桩的完整性分为4类。2）美国规范包括了热异常法，丰富了检测方法。3）美国规范只规定了如何进行试验，一般不规定如何使用试验结果。4）欧洲规范仅提及了完整性检测可采用的方法，并未进行具体规定，一般均按所在地国家标准进行。 |

| 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. |
