FOUNDING HEAVY STRUCTURES ALONG THE SLOPE OF SCHIST FORMATION

Abstract

Placing foundation at different or variable levels below ground can easily be dealt with using renowned structural analysis programs which can work out moments and reaction loads.  However, these software codes may not be equipped with constitutive models that realistically represent the behavior of specific subsurface formation and geological settings. This work presents a case study for a major education institute with many facilities constructed along the slope line of a Schist formation. Inspection of excavations prior to the placement of foundations was carried out. Driving forces and moments were found to pose a significant risk in some parts of the project site and extra safe conditions at other parts and locations. The geological survey and mapping can be a good tool for verifying the support conditions in rock containing laminations and extra thin layers. Physical and chemical properties provide a guide for better design and construction. Precautions and procedure measures to avoid potential slope failures are addressed and outlined.
