...; ACC:Accelerometer). 329 the tunnel was located on the hanging wall side, the damage was almost none in spite of the close approximity of the model tunnel to the projected fault line. However, the tunnel in the footwall side of the fault was subjected to some damage due to relative slip of layers pushed towards...

... Abstract: Blasting is a relatively economical and efficient excavation method compared to other methods such as mechanical excavation. However, when tunnel sites are located near residential areas, the charge weight is often reduced to limit the impacts of vibration and noise. This makes...

... INTRODUCTION The recent earthquakes such as 2016 Kumamoto earthquake, the 2011 Great East Japan earthquake, 1999 Kocaeli earthquake clearly showed that the rock slopes, cliffs bridges and their foundations and tunnels may be quite vulnerable to collapse during earthquakes.
