摘要

The behavior of Reinforced Concrete Box Culverts under varying backfill, compaction, and traffic loads is not clearly understood. The design rules used at present are mostly empirical and do not allow for the effects of Soil-Culvert interaction. In order to have a better understanding of the field behavior of these culverts, in another research study at the Texas Transportation Institute, an 8' x 8' RC box culvert will be instrumented with earth pressure cells and strain gages. The purpose of the study presented in this report is to perform prediction analyses of the behavior of this 8' x 8' culvert, using the finite element computer program, SSTIPN so that the analytical results can be correlated with field observations whenever these become available.
