Research on Model Test of Reverse Self-Balanced Pile Testing Method for Pile Bearing Capacity
As for the application of reverse self-balanced pile testing method in engineering practice,the feasibility of this method is studied through indoor model test.Firstly,the model test device was designed and poured.Secondly,the test data were obtained by conducting the loading tests of pile body and top respectively.Finally,the test results were compared with the calculation result by using the empirical formula method.The research results show that the position of load box cannot provide enough balance force required by two loading at the same time based on the reverse self-balance pile testing method.The results are also affected by the loading sequence and the reserved spacing between the upper and lower piles.In addition,A series of researches must be conducted,which covers the determination of the optimal loading sequence,load compensation,and the determination of the reserved distance between the upper and lower piles.
