Abstract
Aiming at the selection of the reference point in the horizontal displacement measurement of the traditional deep foundation pit support structure
a horizontal displacement measurement method based on the phase laser triangulation principle is proposed. This method can be selected without the reference point in the traditional measurement method. Achieve accurate measurements. Basic principle of the measurement method is introduced and the relevant mathematical model is established
and the computer simulation is carried out to verify the correctness of the mathematical model. The theoretical analysis and simulation show that the measurement method is indeed effective.
