Embodiment Construction
[0040] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0041] see Figure 1-4 , a method for converting the horizontal displacement of a cross-section embankment to monitor the deformation. The specific implementation steps are as follows:
[0042] Step 1: Layout of cross-section monitoring points and acquisition of monitoring point coordinates. The monitoring sections are laid out in the direction perpendicular to the embankment axis, and four monitoring points are arranged in each section, and the coordinates (N i ,E i), i=1, 2, ..., n, where i is the number of the measuring point.
[0043] Step 2: Use the least square method to fit the monitoring section direction line y=ax+b perpendicular to the dike axis, where x is the E (east) direction coordinate value of the monitoring point, y is the N (north) direction coordinate value, and stipulate The straight line direction is from the backwate...
