This paper studies the deformation monitoring method of the main bridge truss of Luoxizhou Bridge.Firstly,a precise monitoring method for truss deformation based on laser scanning technology is proposed,this method can obtain real-time three-dimensional geometric information of the bridge surface and calculate the deformation of the bridge,with high accuracy and a wide monitoring range;secondly,elaborate on the technical principles of this precise monitoring method;finally,the application of 3D laser scanning technology for bridge deformation monitoring under extreme weather conditions in actual bridge projects has shown good results.
