Abstract

"Rock and soil slope movements cost millions of dollars annually. During the past few decades, engineers have relied on traditional methods to detect slope movements. These tools are valuable for small spatial areas but, may not be adequate or cost effective for large spatial areas. Remote sensing methods such as terrestrial laser scanning (TLS) and terrestrial radar interferometry (TRI) provide excellent spatial coverage, and with adequate post-data-processing software, sub-millimetric scale deformation sensitivity can be achieved.

This work will present a comparative experimental study between TLS and TRI. The comparative experimental study will allow us to achieve the two main objectives of this research: 1. The development of a methodology to correct repositioning errors of the TRI during discontinuous measurement campaigns. 2. The development of a methodology to use TLS as an independent measurement device to constrain the results of the TRI when rock displacements exceed multiple wavelengths of the instrument or displacements exceed one quarter of the wavelength of the instrument.

Results from the measurement campaigns show that sub-millimetric displacements can be detected with both TLS and TRI systems. Furthermore, TLS systems are widely available, cheaper, lighter, and easier to operate than TRI systems. Data can also be reduced faster, and the results more easily interpreted than with TRI systems. These advantages make TLS systems ideal for rock slope evaluation for highway projects, especially when time, cost, and public opinion are major concerns for the state's Department of Transportation"--Abstract, page iv.
