SYNOPSIS   

This session focuses on the characterization of Hong Kong marine clay and its implications for reclamation design, illustrated through the Tung Chung East New Town project. Key findings on the properties of marine clay will be discussed, as these are critical considerations for planning and executing ground improvement works.

The case study highlights a range of ground improvement techniques and site trials implemented for the project, including trial embankments with prefabricated vertical drains (PVD) and surcharge, deep cement mixing (DCM), alternative improvement layouts, and rapid impact compaction (RIC) trials. Furthermore, the session will cover the innovative use of DCM to construct gravity walls for temporary works in box culvert excavations.
