Photoelectric integrated testing technology was used to study precast piles during pile jacking at the pile-soil interface considering the influence of the earth and pore water pressures on its vertical bearing performance. The low temperature sensitive fiber Bragg grating (FBG) strain sensors and miniature silicon piezoresistive sensors were implanted in the model pile to test the changes of earth pressure, pore water pressure and pile axial force of the jacked pile at the pile-soil interface, and the influence of lateral pressure on pile axial force was s
