- Inputting the displacements from the Geo5 finite element analysis in to XDISP
- Empirical ground movement curves based on CIRIA C760 case studies of secant piled walls installed in stiff clay (CIRIA C760).
Using the CIRIA C760 ground movement curve for a secant piled wall in stiff clay resulted in a maximum damage category of Very Slight (Category 1). The results of the FEM analysis resulted in a maximum damage category of Moderate (Category 3) – the orange wall in the picture below.
Our challenge was that given that one of the analysis found unacceptable levels of damage to buildings, a more considered approach was required.
