Land reclamation & soil improvement works for a coal-fired power plant in Malaysia

Abstract

The project site is underlain by superficial deposits of recent to sub-recent age alluvium with the upper soil stratum comprising very soft to soft marine clays (Halocene clay) of up to about 25m thick. The reclaimed area on swampy coastal land was pre-loaded with hydraulic sand fill and aided with pre-fabricated vertical drains (PVD) to accelerate the consolidation settlement. This paper presents the design considerations including the important factors for realistic prediction of consolidation settlement and fill embankment slope stability. Emphasis is placed on the monitoring data and their comparison with the design predictions.
