In this paper a knowledge-based clustered partitioning technique is developed for determining reliability index and failure probability of rock wedge. Here, the a reliability index is analyzed and the optimization is carried out using a knowledge-based clustered partitioning (KCP) technique. The reliability index computed with this KCP technique is compared with those using other approaches suc...

As part of the demonstration of compliance with federal regulations, a shaft seal system has been designed for the Waste Isolation Pilot Plant. The system completely fills the 650-m shafts with components consisting of the common engineering materials, each of which possesses low permeability, longevity, and can be constructed using available technology. Design investigations couple rock mechan...

The surface displacement by seasonally freezing bulge and thawing subsidence are main hazards for engineering construction in permafrost regions, especially for the Qinghai-Tibet railway. For detecting the distortion at permafrost area, we try to study the interferometric method of monitoring the deformation at permafrost area with time-series EnviSat ASAR data. In this paper, the coherence cha...

The field of hydrogeology is primarily concerned with the flow of water below the ground surface and with transport, normally of solutes and heat, within that water. Many disciplines have contributed to this endeavor which requires skills from across the spectrum of science, engineering and beyond. The diffusion equation describes not only solute transport but also the flow of water, via Darcy’...

This research was conducted to determine how the incorporation of different poroelastic equations would affect measured rock matrix bulk modulus in laboratory. To do this, three experimental methods were used measure modulus, Ks, seven sandstone specimens taken from Świętokrzyskie mine Poland. Those based on governing poroelasticty theory. The has a substantial impact strength against external ...

In Mars rover missions, a high degree of accuracy in localization of the rover and mapping of the surrounding terrain is of fundamental importance for safe rover navigation and for achievement of scientific and engineering goals. In the Mars Exploration Rover (MER) 2003 mission, ground image-based incremental bundle adjustment (BA) technology has been performed on Earth to correct rover positio...

With the increasing complexity of engineering geological conditions, problem tensile-shear failure bolts is becoming more serious. Accurate modelling performance bolted rough joints subjected to load essential for support design. In this paper, based on theoretical criteria bolt failure, mechanical model Pile element in FLAC3D program modified, and accuracy modified verified by numerical experi...
