Abstract
A centrifugal testing device for simulating ground subsidence induced by buried pipeline leakage and infiltration includes a model box provided with a transparent observation window at a front side, a chamber partitioning plate, a damaged pipeline model, permeable plates, and a water-soil separation device. A front part of the model box is divided into a test soil chamber for filling model soil and seepage chambers located at two sides of the test soil chamber. A rear part of the model box is divided into a soil filtration chamber and water circulation supply chambers located at two sides of the soil filtration chamber. The damaged pipeline model includes a front end provided with an electric push rod for controlling a crack of the damaged pipeline model to be opened and closed and a rear end provided with a ball valve device and connected to a water pump.
