First Experiences with the Deformation Analysis of a Large Dam Combining Laserscanning and High-accuracy Surveying
Monitoring the static and dynamic behaviour of large dams has always been a topic of great importance, due to the impact these structures have on the whole landscape where they are built. Many instruments and surveying methods have been applied so far in order to continuously access to the safety of this kind of huge structures. However, the common approach in a lot of developments has been foc...
متن کاملThe Application of GPS To Dam Surface Monitoring
Dam monitoring relies on the long-term measurement of small structural motions at regular intervals. Traditional surveying techniques and geotechnical instrumentation can effectively monitor oneor twodimensional modes of motion. However, spatial distribution of geotechnical instrumentation is usually limited to the locations that the instruments can be installed during dam construction, whilst ...
متن کاملRadar Interferometry for Monitoring Land Subsidence Due to Underground Water Extraction
The underground water extraction induced subsidence has the characteristics of slow rate, less predictable location and coverage. Over a long time period, the cumulated subsidence can be up to a few metres. This paper demonstrates the feasibility and capability of using conventional two-pass differential interferometric synthetic aperture radar (DInSAR) for monitoring the underground water extr...
متن کاملJoint Terrestrial and Aerial Measurements to Study Ground Deformation: Application to the Sciara Del Fuoco at the Stromboli Volcano (Sicily)
The 2002–2003 Stromboli eruption triggered the failure of part of the Sciara del Fuoco slope, which generated a tsunami that struck the island and the northern coastline of Sicily. The Sciara del Fuoco is a very steep slope where all lava flows from the craters’ emplacement; most lateral eruptions usually take place from fissures propagating in this sector of the volcano. The eruption went on t...
متن کاملA Railway Track Geometry Measuring Trolley System Based on Aided INS
Accurate measurement of the railway track geometry is a task of fundamental importance to ensure the track quality in both the construction phase and the regular maintenance stage. Conventional track geometry measuring trolleys (TGMTs) in combination with classical geodetic surveying apparatus such as total stations alone cannot meet the requirements of measurement accuracy and surveying effici...
