Research on the Improvement and Application of the Measurement Method of Structural Deformation Characteristics in the Construction of Double-tunnel
At present,when using laser technology to explore the settlement characteristics of double tunnels,there are some problems such as point cloud data disturbance,which makes it impossible to accurately simulate the deformation results and determine the deformation location.In order to solve the above problems,this paper select-ed the three-dimensional laser scanning method to carry on the new detection to the subway double-tunnel con-struction stratum deformation numerical value.In this paper,the finite element difference model was established af-ter analyzing the double-tunnel force and detecting the deformation of the tunnel structure,at the same time,the best deformation measurement method was obtained by analyzing the deformation of construction structure of double-tunnel and applied to practice.Based on the analysis of the experimental results,it is determined that the meas-ured results of the deformation of the construction structure of the double-tunnel are accurate to 0.1 mm by using the three-dimensional laser scanning technique,and the deformation positions are displayed on the two-dimen-sional sequence diagram and the three-dimensional deformation diagram simultaneously,good measurement abili-ty.
