GDG was requested by MacKenzie Construction Ltd. to provide geotechnical consultancy services for the permanent remediation works of the Union Canal breach.
The breach is located approximately 2km southeast of Polmont and 4.5km west of Linlithgow in the Scottish Lowlands. The objective of this project is to remediate the canal embankment at the breach location and along areas of the embankment slope that have shallow translational slips along the northern slope.
The purpose of this design was to evaluate a remediation solution for the permanent stabilisation of the canal embankment. This solution includes the reinstatement of the canal embankment across the breach location and installation of sheet pile walls.
This permanent solution includes the installation of:
‘’Mackenzie provided us with some drone footage, and Eoin had a look at the site. It was proper detective work to figure out what had caused it, and then to model it accurately in the design software to produce the same failure to then assess the in-situ parameters and take it forward to assess the permanent works design.”
The assessment of the remediation works was completed using GeoStudio SEEP/W and SLOPE/W 2012, FREW 19.2 and the Plaxis 2D finite element analysis software packages. GeoStudio SEEP/W and SLOPE/W 2012 have been used to assess the hydraulic flow and stability of the proposed remediation works.
FREW 19.2 has been used to assess the geotechnical ultimate limit state actions applied to the sheet pile walls and Plaxis 2D has been used to assess the serviceability limit state ground movements of the remediation works.
