JK Geotechnics completed detailed slope stability analysis (using Slope/W) to assess temporary works soil nailing requirements (i.e. length and spacing) to support the cuts (up to 16.0m deep). JKG also completed detailed analysis of the three permanent RE walls (external stability only) in accordance with the project specific RMS QA Specification R57. The three walls were up to 160m long and a maximum of about 16m high. Analysis was completed to assess global stability (using Slope/W) as well as overturning and sliding using conventional calculation methods and limit state factors.
