Development of large scale pile foundation model test system

In order to make further researches on the new types of piles,a large-scale pile foundation system is established to make full-scale model tests and overcome the disadvantages of small model tests,such as scale effect.The developed system consists of the test room,loading system,measuring system and soils.The preparing method of soils,including control indices,laying methods and result detecting,is introduced.Meanwhile the pile-making method and quality test method are also shown.The final test results show that the quality of the soils can meet the requirements of the following experiments.Furthermore,by use of this model test system,the full-scale load tests on PCC piles are done,and the results indicate that the full-scale pile foundation test is feasible.
