The topic is relevant due to the necessity to improve approaches to estimation and prediction of deformations of structures operating in harsh natural conditions. The article deals with the study of engineering-geological conditions of the area during reconstruction of the viaduct. It is necessary to introduce new technologies, such as laser scanning technology for the construction of an accurate three-di-mensional model of the object, finite element method for prediction of soil behaviour. The aim of this study is an attempt to prove the effectiveness of the method of terrestrial laser scanning over traditional tacheometry. Research Methodology: The initial data for simulation the behaviour of the soil massif were obtained through regional geological works and field study in 2011-2012. In the course of the work 11 wells were drilled, 9 holes were trenched, more than 50 samples were selec-Ted. A reconnaissance survey of the site was completed. A program complex on the basis of FEM is used to forecast the stress-strain sta-Te of soil massif. Laser scanning technology is used for the evaluation of deformations and the construction of accurate three-dimensio-nal model of the object. The terrestrial laser scanning objects held by 3D laser scanner Leica Scanstation C10; horizontal, vertical justifi-cation and binding study points to a local coordinate system using Total Station LEICA TS15 and GNSS receiver LEICA GS10; handling an cloud of points held in the software package Leica Cyclone 8.0; three-dimensional object modeling was carried out in the software pac-kage SolidWorks. The results. Engineering geological conditions of a research site are studied in detail. A digital design model is created. The forecast of stress-strain state of the soil massif in the reconstruction of the viaduct is made.
