In view of the differences of planning of geotechnical investigation requirements between Chinese and foreign standards,comparative analysis and research on planning of geotechnical investigation requirements of Chinese standard (GB 50021—2001 Code for Investigation of Geotechnical Engineering,JTS 133—2013 Code for Geotechnical Investigation on Port and Waterway Engineering)，European standard (Eurocode 7：Geotechnical design) and American standard (ASTM codes related to geotechnical investigation) were carried out.The study found that there were significant differences between the Chinese and foreign survey standards in terms of stage division,content,method,spacing and depth of exploration points,number of trials,optimization during surveying,control and monitoring of construction phases,and other aspects of the planning of investigation.We put forward the application points of overseas geotechnical investigation standards,which will help industry colleagues understand and use overseas investigation standards,and be beneficial to the international integration of Chinese standards.
