The application discloses a non-limit state soil pressure calculation method based on displacement monitoring and relates to the field of soil pressure calculation.The non-limit state soil pressure calculation method based on displacement monitoring comprises the following steps: S1, data is acquired, and coefficients and calculation standards are preset; S2, displacement sensors are arranged according to arrangement rules, and effective displacement monitoring data is obtained by combining collected data; S3, a non-limit state soil pressure coefficient expression is preset, and a displacement soil pressure constitutive model is established; S4, calculation logic is set, and the non-limit state soil pressure is calculated by substituting the model; S5, a threshold value and a calibration rule are preset, the soil pressure is verified and calibrated, and the non-limit state soil pressure is updated; and S6, condition adaptability matching is performed, and a report is generated.The non-limit state soil pressure full-process calculation system is combined with a constitutive model constructed based on an elastic plastic deformation theory of soil to realize engineering adaptability calculation of the non-limit state soil pressure.

The utility model relates to a sliding groove buckle type angle limiting rotating shaft structure which comprises a sliding groove structural part, an electrodeless rotating shaft and a connecting plate. A square shaft is fixed to the center of the sliding groove structural part, an arc-shaped guide groove surrounding the center of the square shaft is formed in the sliding groove structural part, C-shaped plastic buckles are arranged at the two ends of the arc-shaped guide groove respectively, and the opening ends of the plastic buckles face the interior of the arc-shaped guide groove. The center of the stepless rotating shaft is connected with a rotating piece, a center hole of the rotating piece is connected to the square shaft in a matched and sleeved mode, and the stepless rotating shaft can rotate around the square shaft. Positioning columns corresponding to the arc-shaped guide grooves are arranged on the connecting plate, the positioning columns penetrate through hole sites in the circumferential side of the stepless rotating shaft and then are connected with the arc-shaped guide grooves in a sliding mode, and the diameter of the positioning columns is larger than the opening size of the plastic buckle. According to the utility model, by utilizing the elastic plastic deformation characteristic of the plastic buckle and through the interference fit design of the positioning column and the buckle, the accurate positioning of the rotation angle and the hand feeling of passing point force are realized, and the accurate conversion of horizontal and vertical screen angles is realized.
