Model tests in soft rock pile foundation are carried out and the bearing characteristics of soft rock pile foundation of Funing port and their long-term effectiveness are mastered, which provide a basis for the engineering design. In the test of the bearing characteristics in soft rock pile foundations, it is the most critical for us to design the foundation model and the pile foundation model. The related parameters of materials are obtained by similar analysis, test planning and on-site sampling. The materials of the foundation model and the pile foundation model and their mix proportions are determined, which lay the foundation for the next test.
