With the increasing internationalization of geotechnical engineering projects in China and the growth of international engineering cooperation， the demand for referencing and applying foreign technical standards in engineering practice is growing. As a widely used in-situ testing method， the technical requirements and application of plate load test （PLT） results vary across different standard systems. To facilitate international engineering practice and standard alignment， this paper provides a comparative analysis of the similarities and differences between current domestic and foreign PLT standards from three aspects： standard systems， testing methods， and data interpretation. The analysis reveals the following：（1） In terms of standard systems， foreign standards typically focus on specific fields by proposing mandatory provisions and technical requirements， featuring a relatively concise structure. （2） Regarding testing methods， foreign standards are primarily principle-based and guidance-oriented， imposing higher requirements on engineers to conduct tests based on actual field conditions. （3） In data interpretation， domestic standards usually determine the allowable bearing capacity directly from the load-settlement curve. In contrast， foreign standards derive the allowable bearing capacity by back-calculating strength parameters under specific conditions and applying ultimate bearing capacity theories. This study provides a valuable reference for conducting PLTs and analyzing results under foreign standard frameworks.
