MTI/MoDOT Transportation Geotechnics Research Program - Tasks 1 and 3

项目名称：	MTI/MoDOT Transportation Geotechnics Research Program - Tasks 1 and 3
摘要：	This project is one component of a comprehensive research program to develop new and improved load and resistance factor design (LRFD) specifications, and associated commentary documents, for design of bridge foundations and earth slopes. This specific portion of the work focuses on completing an extensive lab and field testing program to quantify variability and bias in relevant design parameters (e.g. shear strength and consolidation parameters) as a function of specific boring, sampling, and testing techniques. Results of this work will also lead to recommendations for improved site characterization procedures for Missouri Department of Transportation (MoDOT). Recommended procedures for establishing appropriate values of variability and/or bias in design parameters based on site specific testing will also be developed. Results from this task are crucial to development of improved MoDOT specific load and resistance factors and to the broader objective of developing design techniques that will reduce costs while maintaining appropriate risk for bridges and earth slopes. This will also provide support for Task 3, which focuses on analyses of appropriate target risk levels for bridge foundations and earth slopes in different conditions. Analyses will include economic and risk analyses to develop preliminary recommendations for target risk levels that achieve a balance between cost and risk. These recommendations will then be vetted among top level MoDOT leadership to invoke agency priorities. Following this vetting process, final target risk levels will be established and subsequently used in other portions of this work to develop design specifications that will achieve the target risk levels.
