A 132.70-m-high tower (above foundation) has been successfully completed at Tenerife Island. The foundation of the tower, a 2-mthick reinforced concrete slab, is supported by jointed, vesicular and weathered basalt, and scoria. A three-dimensional, elastic finite element program has permitted to calculate the displacements of the tower and the stresses in the slab. The installation of rod exten...

Jointed rock masses are frequently encountered during the TBM excavation. To investigate breakage mechanism of jointed mass by disc cutter and precursory information before failure, a series indentation tests were performed on shear rheological test system. During test, breaking process specimens recorded digital image correlation system thermal infrared imager simultaneously. Therefore, strain...

This work uses a combination of simulations performed via numerical models and field observations studied the attenuation deep-hole blasting stress waves evolution mechanism cracks in jointed rock mass. First, we conclude that larger joint angle is, is transmission coefficient smaller fractal dimension. Second, time difference between peak maximum principal on both sides hole horizontal directi...
