[0061] Example one
[0062] Take as image 3 The test model of a tied arch bridge is shown as an example. The main body of the entire arch bridge is a steel structure with a length of 5.2m, a width of 0.875m and a height of 0.646m. According to the proposed method of the invention, the displacement identification of the arch bridge is carried out through the following steps: (1) According to the width-to-span ratio of the bridge, it can be determined that the curve characteristic of axial strain along the beam length is a quadratic curve, so three elements are selected to determine Top sensor layout plan; (2) lay out the 3 units at positions 1, 9, and 18 of the tie beam, and the sensor layout of the structure is as follows image 3 Shown
