Embodiment Construction
[0018] The method of the present invention divides the arch dam into n sections on the same horizontal plane according to a certain relationship, n=0,1...i-1,i,i+1,i+2,...n, wherein i is Natural number. Establish a coordinate system at the intersection of each straight line segment, and use the round point of the coordinate system as a measuring point platform; and set up a laser transmitter and a laser receiver on each measuring point platform, and the laser transmitter and laser receiver are installed at the origin of the coordinate system , the laser transmitter is used to emit the laser beam, and the laser receiver is used to receive the laser signal of the response deformation of the dam; use the corresponding mathematical model to deduce the relationship between each coordinate system, so as to obtain the parameters of the six-dimensional direction. According to the known coordinates of the endpoints, such as figure 2 The "0" points and "n" points in . Through the sen...
