Paper presented at the ISRM International Symposium, November 19–24, 2000
Paper Number: ISRM-IS-2000-108
... ABSTRACT: Liner systems of landfills placed on slopes are subjected to stress due to displacements of waste. Waste displacements result from settlements and from subsidences of waste material in the landfill. By means of finite element analysis an inclined landfill liner system is studied...

... OF HELIKE The splendid city of Helike is said to have disappeared under the sea, with all of its citizens, in 373 BC. The wording suggests ground subsidence, slides, and a tsunami. Judging from literary and historic references Helike must have been a big city on the coast with a famous sanctuary...

The East Rand Metropolitan Transport Authority (ORMET) decided to investigate the feasibility of using this undermined land for the purposes of major road routes. To render this land suitable...
