SIMPLIFIED ANALYSIS OF LONG-SPAN SOIL-METAL STRUCTURES

It is important to accurately estimate soil properties when analyzing and designing long-span soil-metal structures and other soil or reinforced soil structures. The authors perform triaxial tests on reinforced and unreinforced Lake Erie sand specimens. They propose a hyperbolic stress-strain relation to represent the soil elastic properties. Expressions are deduced to assess the modulus of elasticity of the soil as well as the coefficient of soil reaction that is necessary for proper design of soil-metal structures. The proposed expressions are valid for reinforced and unreinforced soils. A simplified finite-element model is introduced for analysis of long-span unreinforced and reinforced soil-metal structures. Findings from the simplified model and those from a plane-strain finite-element analysis are compared. Results are further verified against the results of tests conducted on small-scale models.
