Beirut Breakwater Boosted by Core Penetrometer
01 Aug 2002
The revival of war torn Beirut continues apace, with particularly high levels of activity along the waterfront.
Consultants for a reclamation project in an area subject to liquifaction wished to assess the feasibility of alternative ground improvement preparations, including vibroflotation and vibrocompaction.
Andrews Survey, often called upon to provide geotechnical and survey personnel to work alongside a contractor's own team, conducted in-situ testing which would allow the consultants to assess each set of vibroflotations/ compactions as they were completed to determine the optimum grid pattern. In a 25m by 25m test area along the line of a proposed breakwater, Andrews Survey took 30 CPT measurements 12m into the seabed before and after each compaction from a five-point moored barge.
An earlier phase involved 8 CPT tests in water of less than 5m alongside the harbour wall to supplement data from an earlier study. Here a CPT was deployed into the harbour by crane.
