Simulation testing of a capping for a waste disposal site

摘要

A testing technique for simulating the behaviour under subsidence conditions of a capping for a land waste disposal site. A scale model strip of the capping (29) is located within a casing (13) so as to extend over a fixed member (18) and a movable member (24). The movable member is moved while subjecting the capping strip to a centrifugal effect to simulate subsidence. Movement of the movable member may be in a series of steps or continuous. Water may be sprayed from a nozzle (36) over the capping strip to simulate rainfall and water collection means (14, 15) are provided for measuring the amount of water drained from the capping.
