Work to evaluate the effectiveness of innovative geotechnical slope repair techniques used on UK national highways is summarised. The techniques assessed were the planting of live willow poles, electrokinetic geosynthetics (EKG) and fibre-reinforced soil (FRS). These were used instead of conventional approaches to reduce the overall impacts of various challenges, including environmental constraints (habitat and visual) and access and utility constraints, and to reduce the scale and/or cost of traffic management and traffic delays. Trials have been undertaken over the last 20 years or so, but monitoring was generally limited to just a few years post-construction; longer term evaluation was not generally undertaken. The evaluated success – or otherwise – of the techniques led directly to recommendations for future use, ranging from the development of live willow pole design guidance and specification information, guidance on further EKG trials and cessation of the use of FRS, primarily on environmental grounds but also acknowledging the construction difficulties encountered. Life cycle analysis revealed that each technique provides significant carbon dioxide savings compared with rock fill replacement. More generic lessons learnt from the trials and the practical applications reported were used to produce guidance for future trials of innovative geotechnical repair techniques, including those for slopes.

创新岩土边坡修复技术的评估

总结了评估用于英国国家公路的创新岩土边坡修复技术的有效性的工作。评估的技术是种植活柳杆、电动土工合成材料 (EKG) 和纤维增强土壤 (FRS)。这些被用来代替传统方法来减少各种挑战的总体影响，包括环境限制（栖息地和视觉）以及访问和实用程序限制，并减少交通管理和交通延误的规模和/或成本。在过去 20 年左右的时间里进行了试验，但监测通常仅限于施工后的几年；一般不进行长期评价。评估的技术成功（或其他）直接导致对未来使用的建议，从开发活柳杆设计指南和规范信息、进一步心电图试验指南和停止使用 FRS，主要是出于环境原因，但也承认遇到的施工困难。生命周期分析表明，与岩石填充替代相比，每种技术都可以显着减少二氧化碳排放。从试验中吸取的更多通用经验教训和报告的实际应用被用于为未来创新岩土工程修复技术（包括斜坡修复技术）的试验提供指导。生命周期分析表明，与岩石填充替代相比，每种技术都可以显着减少二氧化碳排放。从试验中吸取的更多通用经验教训和报告的实际应用被用于为未来创新岩土工程修复技术（包括斜坡修复技术）的试验提供指导。生命周期分析表明，与岩石填充替代相比，每种技术都可以显着减少二氧化碳排放。从试验中吸取的更多通用经验教训和报告的实际应用被用于为未来创新岩土工程修复技术（包括斜坡修复技术）的试验提供指导。
