... tunnels, TBM has been more and more widely used for its unique advantages. However, the frequent replacement of cutters caused by cutter wear has greatly affected the construction efficiency of TBM projects. So the research on cutter and cutter head is always one of the most important issues. Mechanism...

... and the countermeasures required for such unstable conditions, it is important to reveal the mechanism of the behavior. The objectives of this study are to find an appropriate numerical modeling to simulate the displacement behavior of a landslide slope due to tunnel excavations and to discuss the mechanism...

..., for instance, gravitational induced deep-seated deformation. The understanding for deformation patterns and associated temporal variation for a slope is then paid high attentions recently. mechanism bank erosion ailiao river topography cross-shaped discontinuity possible influence southern taiwan...

... mechanical behavior and stability of rock mass have been paid much attention. Griggs (1939) was the first to conduct creep test with limestone, shale and siltstone, which have moderate strength. He pointed out that some amount of creep deformation occurred in rocks when the applied load reached to 12.5%- 80...

... ABSTRACT: In the deep underground environment, with the high temperature and high confining pressure, the characteristics of hard rock, such as granite, will transform from brittleness to plasticity. Also, the mechanical behaviors and constitutive relations of the rock have great variation...
