BORUSAN CONTAINER PORT PROJECT

The main goal of the in-situ soil improvement to be implemented is to form a homogeneous crust against liquefaction, to reduce the amount of settlement under static and seismic loads and minimize the differential settlements by improving the soil with rigid Impact® elements at the site reclaimed by using the material dredged from the sea. The sea bottom consists of soft to medium stiff silty, sandy clay layer.

DESCRIPTION

The project area is planned to be a container storage are located at the south coast of the Marmara Sea. A jetty is used for container ships at the western part of the port. There are further coastal protection structures with riprap at the northern and western edge of the port. The design load considered for settlement control was 60 kPa at the site reclaimed by using material dredged from the sea bottom.

SUBSURFACE CONDITIONS

The soil profile is mainly hydraulic fill (characterized by silty, clayey sand) over soft silty clay (CL) over soft to medium stiff silty clay over medium stiff silty clay with embedded sand layers (SM) underlain by stiff to very stiff silty clay.

IMPACT SOLUTION

Approximately 180,000 meters Impact® elements were constructed and installed to penetration depths of about 16m below existing ground surface to provide improved foundation support for settlement control. Piers were installed in a triangular grid spaced at 1.7m below the stockyard and a square grid spaced at 1.5m beneath the container crane beam to mitigate the potential for liquefaction.
