Abstract In allusion to the construction particularity and existing problems for excavation work, on the basis of analysis of visualization of scientific computing, a visual data analysis method of excavation work was studied in this paper. This paper found a way for engineers to use visualization of scientific computing method to solve excavation work data visualization problems. Volume visualization of surface-based rendering has been applied to visualization of excavation environment and voxel-based rendering (Direct volume rendering) has been applied to visualization of excavation data analysis. A direct volume rendering method of excavation data analysis about Runyang bridge anchor-abutment constructed by freezing excavation method (as a former study) is studied and some unusual problems have been found by visualization analysis of excavation work. Volume Data set of excavation work and its structure have been set up. Almost all soil mechanics parameters and soil displacement field have been involved in this volume data. Now we can discuss soil behavior at anytime of excavation session. A complete visualization analysis system of excavation work is given, by which we can study whole process of excavation work with visualization analysis method.
