Visualization of Civil Infrastructure Emphasizing Geomaterial Characterization and Performance

Abstract

With the advancements made in the spatial analyses, characterizarion methodologies, and management of large data sets, the visualization of geomaterial properties at different stages of civil infrastructure works has become easier to implement. Visualization of material characteristics in the ground has given engineers a realistic three-dimensional image that creates a comprehensive digital ground environment where large complex projects can be effectively conceptualized, designed, and constructed. This research paper presents these material characterization–related advancements made in the better understanding of construction and performance of infrastructure using geospatial and visualization tools. Infrastructure case studies ranging from material characterizations from laboratory and in situ tests to data captured from photogrammetry-based measurements from unmanned aerial vehicle (UAV) platforms are described. The two-dimensional visualization models developed for a pipeline and dam infrastructure provided localized critical zones, which can trigger failure in the event of hazardous conditions. The three-dimensional models, developed using UAV-based photogrammetry studies, provided the health conditions of the structure with a focus on material performance. Future applications encompassing material properties to field measurements are covered in detail.
