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

建议的研究计划有望加强对荷载对复合土钉体系工程行为影响的基本理解。它将为设计假设的试验评估和土钉系统性能的工程评估提供初步的模型比例尺数据。预计这将大大有助于改进设计实践，从而增强工程师对土钉作为一种具有成本效益的工程解决方案的潜在应用的信心，该解决方案可用于桥梁桥台的修复和/或施工，以及在已建成的拥堵城市环境中的补救和土工建设项目。

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.
