Abstract

The topic is relevant due to the necessity to improve approaches to estimation and prediction of deformations of the lighting mast. The solution of this problem is associated with many uncertainties, such as the lack of laboratory studies of the materials properties and field static and dynamic tests of such structures, the small number of analytical studies and monitoring data. The article presents the ini/ tial results of field studies of the high/mast lighting tower deformations and the numerical analysis of its stress/strain state. This study aims to assess the stress/strain state of the foundation of the structure and compare the results of numerical simulation with the data on object deformation obtained during laser scanning. Object of the research is the stress/strain state of the foundation of the lighting mast at the Vankor oil field. Methods. The initial data for simulating the structure behaviour were obtained through archive data and field study. A reconnaissance survey of the site was completed. A program complex based on FEM is used to forecast the stress/strain state of the structure. Laser scanning technology allow accurate definition of deformations lying on every side of the structure and make an accurate three/dimen/ sional model of the object. The terrestrial laser scanning objects held by 3D laser scanner Leica Scanstation C10; horizontal, vertical justi/ fication and binding study points to a local coordinate system using Total Station LEICA TS15 and GNSS receiver LEICA GS10; handling a 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. The stress/strain state of the foundation of the lighting mast was studied in detail. A digital design model is created. The sections and general crack formation together with TLS measurement indicate that the structure is deformed. We estimated the mini/ mum contribution of soil conditions to the deformation of the structure.
