A floor rock roadway under an oblique straddle working face is a typical dynamic pressure roadway. Under the complex disturbance of excavation engineering works, often undergoes stress concentration and severe deformation damage. To solve problem surrounding stability control for this type, study considered East Forth main transport in strata 1762(3) Pansan coal mine. In situ ground monitoring ...

with the growing population and density in metropolitan areas, higher tendency to live in high-rise buildings, and increasing demand for parking lots, it seems necessary to excavate soil to construct underground spaces. during excavation work, as the height of the wall increases, special care should be taken to the wall stabilization to avoid any consequent damage including extensive property d...

Abstract The vibration velocity and frequency of rock mass are closely related to the instability failure building. step topography has great influence on blasting wave propagation. Therefore, it is significance study dynamic response subjected load. In this paper, FLAC2D program used plane strain mode adopted in calculation, load assumed be a triangular pulse which applied one side calculating...

The Brazilian Test is the most used test to determine indirect tensile strength for brittle materials like concrete. It has been observed that success of depends on cracks initiation point position and therefore arch loading angle; a crack appears in center disk when valid. To this effect, using Fast Lagrangian Continua code FLAC2D; numerical analyses were performed study impact angle initial c...

Low height embankments are widely used as road for highways and rural roads in India. Sometimes, the construction of such types on soft foundation soil becomes mandatory. In addition to problematic soil, seismic excitation might also play a significant role stability an embankment. The present study analyses response low embankment with under earthquake loading. Numerical simulations have been ...
