Sustainable design at transition rigid piled embankment with surcharged vertical drain over soft ground

the repair of undulating road involves enormous time and high cost for repetitive remedial works over the time. intolerable differential settlement is the main cause of the undulating roads. differential settlement frequently occurs at the intersection of different ground pressure, ground condition,...
