Abstract
In the course of construction of a large dry dock project in Singapore, an 8-m high cofferdam embankment was constructed by end tipping decomposed granite material into the sea. At the time of dewatering the cofferdam, large movements of the embankment occurred, and electro-osmosis was chosen as a rapid stabilization technique. The electrode layout, which was chosen after a field test, enabled stabilization to be achieved with a low power consumption of 0.5 kWhr/m³ of soil. The success of this operation has been attributed to the relatively high cationic concentration in the boundary layers of South East Asian clays.
