A Hybrid Method of Determining Deformations of Engineering Structures with a Laser Station and a 3D Scanner

Abstract

The article presents the technology and an analysis of results of engineering structure displacements and deformation measurements. Two measuring technologies using the TDRA65000 laser station from Leica and the FARO Focus M scanner were applied during the tests. Use of the laser station enabled us to define horizontal and vertical displacements of a control network established on the tested facility. Owing to this, it was also possible to transform scanner measuring stations into one integrated unit. The described measurement methodology ensures a high accuracy of scanner station fitting which translates directly into the accuracy of determination of deformations in structural components of a facility. Integration of methods applied in the tests makes it possible to monitor not only displacements of control network points but also the structure as a whole in a uniform coordinate system.

Measuring Displacements in Engineering Structures by Means of a Coordinate Laser Station

Abstract

The application of geodetic methods to examine structures consists in the determination of their displacements relative to an established geodetic reference datum or in the definition of the geometry of their individual components. Such examinations form a picture of changes happening between specific points in time. Modern measurement technologies used in geodetic engineering enable undertaking more and more challenging measurements with increasing accuracy. The purpose of this article is to present a measurement technique involving a Leica TDRA 6000 total station to measure displacements in engineering structures. The station features a direct drive technology to achieve an accuracy of 0.25 mm in 3-dimensional measurements. Supported by appropriate software, the unit makes a perfect instrument for the monitoring of civil engineering structures. The article presents the results of measurement of static and dynamic displacements in a few engineering structures. The measurements were carried out both in laboratory conditions and on actual, operated civil engineering structures.

Optimization of Measurement Points Choice in Preparation of Green Areas Acoustic Map

Abstract

The aim of the article is to analyze the selection of measuring points of sustainable sound level in the spa park. A set of points should allow to make on their basis an acoustic climate map for the park at certain times of day by usage available tools. Practical part contains a comparative analysis of developed noise maps, taking into account different variants of the distribution and number of measuring points on the selected area of the park.

Analysis of Vertical Displacements of the Esperanto Footbridge in Bydgoszcz

Abstract

The subject of the research is a footbridge across the river Brda in Bydgoszcz. The measurements of the footbridge displacements with the test load were undertaken. The paper presents the results of the measurements and compares them with the theoretical results obtained using the finite element method (FEM). On this basis, discrepancy between actual work of the structure and numerical simulations was found. Attempt to explain the reasons for the observed differences and direction of further research were included in the conclusions.

The Study of Using Gis Tools in Sustainable Management of Solar Energy

Abstract

Resource efficiency is the primary element of the European Union's ‘Europe 2020’ strategy for the economic growth. It aims at stimulating economic growth which will be smart, sustainable and inclusive. Proper land use is beneficial to the economic development and it contributes to the improvement of living conditions considering the principle of sustainable development. Geographical information systems are the perfect tools enabling effective spatial planning. GIS technology allows to carry out complex analysis, which enable a comprehensive environmental and urban assessment. Using GIS tools gives also a possibility to assess different variations of land use in the future. The article presents the results of the analyses carried out on the basis of DTM and DSM, which purpose was to assess the potential of solar energy of the selected area. It was shown the possibility of using the roof surface of old buildings in a chosen part of Bydgoszcz to install solar systems on them.
