The Press-in Method with Augering - Augering Area in Relation to Retaining Wall Design-

抄録

When retaining walls are designed, design parameters of undisturbed soil are normally used. In reality, if the retaining wall is comprised of piles, they are often installed assisted by ancillary equipment, such as water jetting or augering, to reduce installation resistance. To what extent the impact of these ancillary methods have on the soil and effect the retaining wall design is not known. This report features impacts of driving assistance of pile installation on retaining wall design. A project in the UK was used as a case study to observe if the design of a cantilevered retaining wall is still satisfied, despite a local ground disturbance by augering in the case of cohesive soil.
