Abstract: This paper compares the ASTM and Chinese standards about plate loading test. It summarizes their main differences in the following two aspects: plate size and steady standard of settlement. It analyzes that two aspects can bring about effect for test result, and puts forward interrelated attentive issue during project. ASTM standard is more universal and greatly flexible. The Chinese standard is detailed and rigorous. The plate load tests in Botswana power plant are carried out according to US standards and Chinese standard respectively. The test results indicate that the differences between two test results are not obvious for high strength formations(for example sand soil).The results can be used as reference for Chinese surveyors and designers in their overseas projects.
