The geological environment along the Sichuan-Tibet railway has characteristics of plate splitting, frequent disasters, complex topography, large cold climate, high and anoxia, etc. It is recognized by world as one most difficult projects so far. Based on construction tunnel entrance steep slope Railway, this paper conducts research construction, reinforcement protection slopes. integrated” syst...

Purpose. A methodology development for predicting the geomechanical situation when mining an ore deposit with steep-dipping layers, taking into account uncertainty in determining rock properties, which is a consequence of mass heterogeneity. Methods. The assessment open-pit wall stability based on combination numerical simulation stress-strain state (SSS) and probabilistic analysis. finite elem...

The present study was carried out to determine the possible origins of sediments entering Taleghan Dam in northern part of Iran, in order to avoid further sedimentation and helping in extension of the useful life of the proposed dam. This was performed by XRD analysis. To do so, first of all, sediment sampling points were positioned along the Taleghan River. The collected samples, after coding,...
