Finite-Element Analysis of Time Domain Reflectometry Cable-Grout-Soil Interaction
Publication: Journal of Geotechnical and Geoenvironmental Engineering
Volume 130, Issue 3
Abstract
Three-dimensional finite element analysis is combined with field and laboratory measurement of time domain reflectometry (TDR) cable-grout response to analyze the interaction between the cable, grout, and surrounding soil mass during localized shearing. Finite element (FE) model parameters for the cable and cable-grout interface elements are back-calculated by matching results from laboratory shearing tests to FE calculated response. These parameters are employed in subsequent FE model geometries to model the behavior of TDR cable-grout composites in soft soils. Optimal grout and cable design is determined by analyzing the relationship between grout strength and stiffness and calculated cable shear stress.
