I-25 T-REX Project: Instrumentation of Caisson Retaining Walls: A Case Study
Publication: Geotechnical Engineering for Transportation Projects
Abstract
This paper presents the design and instrumentation case study of two caisson retaining walls for the T-REX Project in Denver, Colorado. A study of design methods available for caisson cantilever retaining walls indicated that uncertainties exist in selecting the appropriate load conditions, group reduction factors, and even the method of analysis for design of caisson retaining walls. Due to schedule and deflection constraints, the designers decided to utilize a computer program called LPILE to aid in the analyses. However, there was very little information available to aid in the actual use of LPILE to analyze caisson retaining walls. Due to this uncertainty, the design team decided to instrument several key caissons walls for lateral deflections in order to optimize the design process.
