General
This working plan covers the
implementation, integration and data fusion of the results from the new
measurement technologies with the traditional survey methods in order to
reach higher reliability and quality of the final results, to ensure
safety operation. Commission 6 will consist of 4 Working Groups.
Commission 6 is divided into working groups profiled in specific areas of
the engineering survey, data acquisition and analysis. Their work can be
used for the FIG contribution to respond to the structural monitoring,
predicting of deformations of natural and artificial structures and to
prevent building collapses and disasters.
Working Groups
Working Group
6.1 – Deformation Monitoring and Analysis
Policy Issues
Deformation
studies in Engineering Surveying are based on a broad knowledge of
suitable sensors and their potential, modern data storage and
communication solutions and advanced processing and analysis methods.
Additionally a thorough understanding of the behavior of monitoring
objects (large scale structure or landslide effected area), is essential
to set-up and operate an optimum monitoring system. Nowadays deformation
tasks are more and more oriented towards real-time systems, which require
automation of data capture and new concepts in data processing, analysis
and interpretation.
WG6.1’s main goals will be to support specialists in
deformation studies with state-of-the art solutions and provide latest
developments and future oriented concepts:
Support studies on the
potential of existing and new sensors to determine geometric deformation
quantities from surveying and adjacent fields (such as geotechnics).
Support the development of concepts for automated data storage, data
transfer and data pre-processing.
Support the adaptation of numerical
algorithms to derive relevant deformation quantities in real-time,
including concepts from time series analysis.
Support a
multidisciplinary collaboration between surveying, structural and
geotechnical engineers to understand the behavior of structures and
geotechnical objects.
Study of most modern concepts for data analysis
(e.g. artificial neural networks, fuzzy logics and generic algorithms).
Initiate investigations to extend the range of deformation studies to
higher frequencies, specifically in Structural Health Monitoring (study of
oscillations and vibrations and their effects on critical structures).
