摘要

Soil nail walls have been used as retaining structures since the early 1970's. The technology is particularly well suited for constructing walls in areas next to existing abutments, such as highway bridge underpasses, and in areas with steep side slopes where excavation for backfill behind conventional walls may involve large quantities. However, designers have been reluctant to experiment with soil nailing in areas with cold-weather climates and frost-susceptible soils, due to lack of quantifiable data on the behavior of these walls when subjected to freezing conditions. This report documents the performance of a soil nail wall project constructed along Rte 1 in Brunswick, Maine. Selected components of the wall were instrumental to determine the effects of freezing winter temperatures on the wall and surrounding soil. After one winter (warmer than average) there were no adverse effects of frost on the wall.
