Integrate the asset management framework (AMF) for slope maintenance and repair activities, with load and resistance factor design (LRFD) procedures for design of earth slope. Sub-objectives include --Enhance current LRFD procedures to account for bias and correlation --Develop load and resistance factors for risk levels established by AMF --Evaluate the integrated systems via application to case histories --Develop practical application guidance and technology transfer material Abstract Asset Management principles and systems share common goals and objectives with Load and Resistance Factor Design (LRFD) techniques. Asset management seeks to facilitate cost-effective maintenance, upgrade, and operation of physical assets in a systematic way. LRFD methods seek to produce cost-effective design decisions based on rational evaluation of performance, rather than judgment and experience of individual designers. Despite similar goals and objectives, there has to date been no attempt to integrate, or even relate, these techniques and they remain as essentially independent approaches. The project proposed here seeks to integrate the techniques specifically for the design and management of earth slopes and earth retention. Potential Benefits of the Project Potential to extend to other applications such as pavements, bridges, tunnels, and other applications where both asset management and LRFD techniques are currently utilized. |
