Through the evaluation and analysis

Through the evaluation and analysis of the design, construction and pressure test process of the test pile, the mechanical principle, the mechanism of pile-soil interaction, parameter evaluation and bearing capacity estimation of the pile test results in the design process and static load pressure test process of the test pile are studied in depth. The calculation methods of the axial stress of the pile body, the friction at the pile end and the resistance at the pile end are put forward. At the same time, the calculation of ultimate bearing capacity of rock socketed pile is mainly studied through the test pile and the classical limit equilibrium theory.。
