The influence of different loading interface sizes on the accuracy of sand standards was investigated.The re-sults show that the soil pressure calibrated using the large-sized loading interface method is basically consistent with the actual value,with fitting correlation coefficients above 95％,and the sand standard coefficient and oil standard coefficient are in good agreement.The calibrated miniature earth pressure cell was used for single pile model testing,and it was found that the measured soil resistance around the pile was basically consistent with the soil resistance calculated by the pile ben-ding moment.This study has important reference value for the accurate determination of soil resistance in horizontal load-ing model tests of pile foundations.
