... of the slopes. As the valley incision depth increases, the position of tensile stress concentration area in right slope has changed from inside to surface, and lastly to the top of overlying fault. Stress state of left slope is complex and mainly performs tensile stress, but it also shows different...

... with backfilled soil. After a comparative analysis of the monitoring data, the authors define the key controlled zones of rock unsymmetrical deformation and stress concentration, they advise some effective measures to avoid partial tunnel destruction. Through monitoring the blasting vibration on key controlled...

... or pore pressure, then overcomes the compressive borehole stress, and tensile stress concentration will appear preferentially at the notching tip as pumping continues. Fractures are initiated along the tip as concentration stress reaches the tensile failure stress of the rock medium. Reservoir...

... stress is released, new stress concentration is formed and stress is transferred. Through the analysis, it can provide the theoretical basis for studying the crack extending and evolution law of the rock and forecasting and predicting the instability failure of the rock system. 1 INTRODUCTION Rock...
