Abstract:
Specifications for traditional auger mixing methods have made use of the Blade Rotation Number (BRN) to establish acceptable levels of mixing. Cutter Soil Mixing (CSM) has no such established parameter. Previous research has proposed the adoption of an Energetic Mixing Index for CSM, and has attempted to establish a basis for this utilizing results from a limited number of trial panels. This paper reviews the basis if this previous proposal and assess the applicability and validity of the proposed index utilizing a review of production data from a number of sites in the vicinity of Vancouver, British Columbia, Canada. As a result of the review of the data, the paper proposes adoption of a new, CSM specific index, termed the CWRN.
