Engineering Office DENBOER CCI Construction Period 01/2014 - 12/2014 As an improvement to a waterway in the Netherlands, we have installed several kilometres of sheet pile. The sheet pile turns around 3 m of ground and has anchors. At a certain point several cables crossed the sheet pile, along a scope of 11.2 m. The sheet pile could not be installed in the fixed sand packet, so we had to develop an alternative construction. Along the scope we applied a framework at a low level. This framework receives a load of 11 tons per meter of scope and divides it to the adjacent sheet piles that could be installed in the fixed sand packet. The framework, with a height of 1.34 m, was modelled with 1D elements. The sheet piles that were used to hold the framework were modelled with 2D elements. The reactions from the framework were modelled as loads on the sheet piles. The challenge in the project has been the interaction between the different elements. On one side there was the deforming framework, while on the other side the deforming holding construction was an issue. Locally we accepted plastic deforming components, as long as the entire construction held. Through the model we created a complete picture of the expected effects and an efficient and practical design.
