Abstract

Sheet pile cellular cofferdams (retaining walls) are robust structures, capable of withstanding significant deformation without collapse. Traditionally their use in the construction process has been associated with temporary works, but increasingly there is a demand to make use of this type of structure as part of the permanent works. However, although the design of cofferdams to resist static loads is relatively well documented, there are few examples in the literature of design approaches for seismic conditions. This paper describes the seismic design process for cellular cofferdams, drawing upon case histories in the US, CK and Japan. Comparisons are made with the seismic design approach for large retaining structures, particularly those where movement is tolerable.

Seismic Design of Cellular Cofferdams

St. Louis, Missouri

Sheet pile cellular cofferdams (retaining walls) are robust structures, capable of withstanding significant deformation without collapse. Traditionally their use in the construction process has been associated with temporary works, but increasingly there is a demand to make use of this type of structure as part of the permanent works. However, although the design of cofferdams to resist static loads is relatively well documented, there are few examples in the literature of design approaches for seismic conditions. This paper describes the seismic design process for cellular cofferdams, drawing upon case histories in the US, CK and Japan. Comparisons are made with the seismic design approach for large retaining structures, particularly those where movement is tolerable.
