| 摘要： | The Barron Mountain rock cut is located along the northbound lane of I-93 that was constructed in 1972, approximately 60 miles north of Concord, NH. In response to a rockslide that occurred during construction, approximately 250 rock reinforcements consisting of grouted, high strength steel rods were installed along the 800 ft. long, 130 ft. high cut. The New Hampshire Department of Transportation (NHDOT) is concerned with the longevity of the system because more than half of the generally accepted 50-year design life has passed. The NHDOT engaged McMahon & Mann Consulting Engineers, P.C. (MMCE) to perform an initial condition assessment, estimate the remaining service-life of the rock reinforcement, and make recommendations for more detailed condition assessment and future monitoring including invasive testing. This report describes MMCE's approach, and the findings, conclusions and recommendations resulting from the study. |
