Abstract:

To enable prediction of the response of systems with corrugated-metal arches and compacted soil bridges to soil loading above crown level, graphs were developed from a large number of finite-element analyses. The graphs are based on analysis of a flexible arch in the form of a half ellipse supported on either side by typical footings. They facilitate prediction of response parameters as the fill is placed and compacted in layers above the crown level. The material surrounding the arch is considered homogenous in terms of elastic modulus and Poisson's ratio. Although the graphs are based on linear analysis, important nonlinear effects may be taken into account by application of the graphs in a stepwise manner. Comparison of predicted response with that from a specific finite-element analysis of a field structure suggests that the errors introduced by idealizations associated with the graphical approach may be insignificant for many projects. In addition, comparisons of predictions with field measurements show encouraging results. (Author)
