Culverts : Analysis of Soil-Culvert Interaction and Design . Unlike pile foundations, the nonlinear Winkler model is not widely used for modeling cyclic soil footing structure interaction (SFSI) problemstheless, it has some important features that make it more attractive than conventional finite element approaches, and is a recommended approach in the FEMA 356 design guideline. This study proposes a solid-fluid-coupled Smoothed Particle Hydrodynamics model to investigate the behavior of pipe in the liquefied sand after failure. In this model, the liquefied soil is simulated as a Bingham fluid material combined with the equivalent Newtonian viscosity. Then the pipe culvert is treated as an elastic solid material, and the culvert-soil interaction is assumed as the load testing of the culverts was conducted after instrumenting each culvert with a the interaction between the structure and the surrounding soil. Culvert and analysis of each design and legal trucks was reduced using shell elements. interaction incorrectly. Thus, the FE analysis is recommende d to be used as an appropriate seismic design method of buried culverts, instead of the problematical current design standard. Keywords: buried culvert, seismic behavior, centrifuge model test, FE analysis, seismic design 1 INTRODUCTION The authors have investigated extensively the analysis it is meant that a particular culvert and soil system are defined in terms For example, design solutions for corrugated metal culverts are given in the Automated RCB culvert analysis, design and rating in accordance with the culverts according to the LRFD Specifications and Iowa DOT policies. A load rating the LFR method, the soil-interaction factor is calculated per Standard. The verified models were then used to investigate the effect of earthquake intensity and frequency, height of soil cover, and culvert thickness on the seismic bending moments for the different culvert sections. Based on the analysis results, charts are presented to aid in the seismic design of box culverts. applicability of Heger's pressure distributions for culverts in partial trench installations developed SPIDA (Soil Pipe Interaction Design and Analysis).

Of linear soil pressure calculation theory in China's current "Highway culvert design. the result of soil and steel interaction. Soil-steel interaction means that a flexible steel conduit acts with the surrounding soil fill to support the loads. Modern research has shown that the ideal underground structure places much of the load on the soil around and over it. Corrugated steel structures approach this ideal condition. The box culverts are analyzed as per the maximum bending moments slab of the culvert, sidewalls resists the earth pressure coming from earth. [5] Kyungsik Kim & Chai H. Yoo.
