Soil Nailing - Innovative Rehabilitation Technology for Widening and Repair of Bridge Retaining Structures

本文的研究成果将有助于加深对复合土钉支护结构工程特性的认识。它将产生初步的模型比例数据的设计假设的实验评估，并为土钉系统的性能的工程评估。预计这将大大有助于改善设计实践，从而提高工程师的信心，在潜在的应用土钉作为一个具有成本效益的工程解决方案的修复和/或建设的桥台，以及修复和岩土工程建设项目在建成拥挤的城市环境。

The proposed research program is expected to enhance the fundamental understanding of loading effects on the engineering behavior of composite soil-nailed systems. It will yield preliminary model scale data for the experimental evaluation of the design assumptions, and for the engineering assessment of the soil-nailed system performance. It is expected to significantly contribute to improve design practice and, thereby, to increase the confidence of engineers in the potential application of soil nailing as a cost effective engineering solution for rehabilitation and/or construction of bridge abutments, as well as for remediation and geotechnical construction projects in built congested urban environments.
