The Displacement Models Of The Lusi Mud Volcano Embankement Dams Using FEM

Abstract

Soil embankment dams have been built surrounding the Lusi Mud Volcano in Sidoarjo, East Java, to keep hot mud within the ponds since May 2006. The dams have been made of soil materials sitting on poor weak grounds. A finite element method (FEM) was applied for modelling the displacements of the embankment dams. Results show that the dam displacements in both vertical and horizontal directions were high in static and dynamic state conditions. The final design of the dams had a total displacement of about 1.3-1.9 m in both static- and dynamic-state conditions.
