Model pile body internal force rating device and method
The invention discloses a model pile body internal force rating device and method. The model pile body internal force rating device comprises a vertical frame, wherein the bottom of the vertical frame is provided with an axial loading device; the axial loading device is provided with a model pile; the middle of the frame is provided with a horizontal loading device; loading sensors are arranged in the axial loading device and the horizontal loading device respectively; the model pile is provided with a strain sensor; the loading sensors and the strain sensor are connected with a control center through a strain collection instrument; the control center is in control connection with the axial loading device. According to the model pile body internal force rating device and method, the accurate axial loading is performed on the model pile through a small hydraulic jack and strain values of different positions of strain pieces of the model pile are measured to obtain the axial force rating coefficient between the strain of every strain piece and the axial force of a corresponding position of pile body; a concentrated load is applied to the middle section of the pile through a pulley and the strain difference of the strain pieces of the section of the model pile is measured to obtain the bending moment rating coefficient of the strain difference of the strain pieces and the bending moment of the section of the pile body; the internal force of the pile body can be accurately determined.
