Abstract: Due to the traditional control method, the stress-deformation controller adopts the single-channel mechanism to operate during the stress and deformation control of road and bridge construction, so the control deformation is high and the stress and deformation control of road and bridge construction cannot be realized. In order to solve this problem, a method of controlling the stress and deformation of road and bridge construction based on IOT technology is proposed. The pre-stress of road and bridge construction is calculated by empirical formula and written into the instruction set of RISC-A; By considering the stress-deformation relationship of road and bridge construction as a curve relationship, the deformation amount of the road and bridge is calculated and substituted into the IOT stress-deformation microcontroller; Programmability of IOT technology defines a MAC enhancement mechanism that providing global collaborative control function for design methods; The bearing capacity of the bridge under the strain value is calculated, and the control instruction is given according to the corresponding bearing capacity, so as to improve the accuracy of the stress and deformation control of the road and bridge construction. Analysis of design examples shows that the design control method can control the deformation to a minimum of 0.158mm, while the control group controls the deformation to a minimum of 0.654mm. The design control method can achieve road and bridge construction stress and deformation control.
