Volume Six - Pre-Victorian to the Present Day - Select Aspects - Structural Analysis of the river Ely Subway by Rota Design Limited - 2015

A cross sectional view of the subway with water and soil - worst case assumed.
   

The finite element model

The first plot is the finite element model of the cylindrical subway showing the mesh used for the initial analysis.

   

The subway displacement under load

This plot shows how much the cast iron segments of the subway deform when they are subjected to the load of soil and water - not much! Just like very gently sqeezing our empty lemonade can again.

   
A second plot of displacement to verify the direction of deformation.
