3-D COMPUTER MODELING OF SUBSURFACE CONDITIONS FOR BRIDGE FOUNDATIONS

A study was conducted to evaluate the potential for using three-dimensional (3-D) computer modeling to assist Missouri Department of Transportation Soils and Geology personnel and Bridge Division personnel in developing accurate and realistic understanding of subsurface conditions for bridge structures. Secondary objectives of the study included developing a preliminary procedure for development of 3-D geologic models of bridge sites and identifying key issues to be addressed for more widespread use of 3-D modeling activities. The site of a proposed new bridge across the Missouri River near Lexington, Missouri was selected as a demonstration case study for 3-D geologic modeling. Several separate models of this site were developed during the project to demonstrate the different levels of abstraction for a 3-D model of a particular site. The computer models developed are presented and described in this report. The models developed for this project illustrate the types of 3-D computer models that can be generated using currently available software. It is recommended that an expanded pilot program be implemented to include modeling of several additional sites. The expanded pilot program should include modeling of geologic conditions during site investigation and should be performed by personnel that are intimately involved with site investigation activities. In addition, interim versions of 3-D models developed during site investigation should be used to assist in selecting locations for additional borings.
