GIS-based kinematic stability analysis in rock slopes is a rare practice geological engineering despite its immense potential to delineate unstable zones mountainous region. In this article, we have used modified technique assess the efficiency of predicting shallow landslides Himalayan mountains on regional scale. The limited use primarily due complexities involved practical application. To ma...
With the continuous downward mining, more and attention has been paid to problem of slope stability under open-pit combined mining. Taking Zijinshan gold copper mining as an example, failure properties overlying rock mass different methods are studied by numerical simulation method, law is proposed. Combined with geological structure distribution 5-5 section influence stages, evaluated slip fie...
Fluid pressures in Miocene-Pleistocene sediments of the US mid-Atlantic continental slope approach the lithostatic stress and are an important control on the stability of the slope. Fluid pressures in excess of hydrostatic were generated by regional depositional patterns and sedimentation rates. Fluid migration within porous and permeable Miocene silty sand layers redistributed pressure and gen...
Nacrtak Forest roads provide access for people to study, enjoy or contemplate natural ecosystems. Therefore, roads are one of the most important tools needed in forestry. Forest roads are built by excavation of soil and rock. Rockfall occurs during construction works, caused by excavated rock pieces on embankment slopes and by blasting of block rock masses. This study analyzes rockfall damage t...
This paper presents a case study of geotechnical design of bridge foundations and approaches in hilly granite formation in northern New South Wales of Australia. Firstly, the geological formation and existing cut slope conditions which have high risks of rock fall will be described. The bridge has three spans to be constructed using balanced cantilever method with a middle span of 150 m. After ...
Considering the fact that rocks fail faster under tensile stress, rock tensile strength is of greatimportance in applications such as blasting, rock fragmentation, slope stability, hydraulic fracturing,caprock integrity, and geothermal energy extraction. There are two direct and indirect methods tomeasure tensile strength. Since direct methods always encompass difficulties in test setup, indire...
while sophisticated analytical methods like morgenstern-price or finite elementmethods are available for more realistic analysis of stability of slopes, assessment of the exactvalues of soil parameters is practically impossible. uncertainty in the soil parameters arisesfrom two different sources: scatter in data and systematic error inherent in the estimate of soilproperties. hence, stability o...
