Experimental study on stability of a caisson type quay wall by the artificial drain method using recycle material during earthquake

In order to improve earthquake-proof capacity of a caisson type quay wall, a series of shaking table model tests was performed using the new artificial drain system as a countermeasure against soil liquefaction. The tests were conducted under earthquake input motions, making the maximum acceleration...

Description
Summary:In order to improve earthquake-proof capacity of a caisson type quay wall, a series of shaking table model tests was performed using the new artificial drain system as a countermeasure against soil liquefaction. The tests were conducted under earthquake input motions, making the maximum acceleration level change. The results from these experiments indicate that the drainage provided by recycle artificial drains can significantly reduce pore pressure generation and deformation of the caisson type quay wall. The present study also shows that drain method is useful even under strong earthquake shaking to protect the horizontal movement of the caisson structure.
