Observed Performance of Soil Nailed Walls in Korea Based on Field Measurements

摘要

Observed performance of soil nailed walls in Korea based on a number of field measurements has been investigated. The investigation has covered interface shear stress development at the nail-soil interface from pull-out tests, lateral ground displacements, tensile force distributions in soil nails and back-calculated interface shear stress distributions along soil nails. Insights into the soil nailed wall behaviour based on the shear transfer mechanism at the soil-nail interface and partial mobilisations of the interface shear strength are reported and discussed.
