Abstract-InfluencedINTRODUCTION The most direct and reliable way to study the vertical bearing characteristics of pile foundation is the field test. For the construction of pile foundation, the test conditions are relatively good, can make the field loading test for pile foundation pile test, but for the service, due to the long-term operation, the monitoring data acquisition and strain gauges embedded were not convenient, and the field test is costly, time-consuming, large occupied area, and the key is the pile test is not repetitive, so the collected data is relatively small. Model test has its unique advantages, and it is a common method to study pile foundation problems. Due to the geometry size of the model test is small, so the specimen is made easy, convenient handling, material saving, labor and
