Nonlinear Least Squares Phase Unwrapping Based on Topographic Slopes
Journal of Geo-information Science, 2013Interferometric synthetic aperture radar(InSAR) phase unwrapping is one of the key technologies,which,uses the InSAR interference phase,to extract digital elevation model or accurate differential interferometry.However,affected by the porblem that the terrain is streep or the slope is larger,the unwrapping result is bad and causes error transmission in

Influence of topographic roughness on the stress state in a sloped rock-mass
2006Although stress states in the ground are seldom well known with precision, such is especially true in slopes where the boundaries and initial conditions as well as topographic variations are difficult to grasp. As with other sites, it proves difficult to replicate the history of the tectonic stages the ground has undergone.

Topographic Effect on Seismic Slope Behavior in a Shaking Table Test
2012Statistical analysis of the spatial occurrence of slope instability features due to the 2008 great Wenchuan earthquake has shown the remarkable lithological and topographic effects, and seismic parameters play an important role in spatial distribution of geo-hazards. As the slope response to seismic waves is only poorly understood, the present research
