Abstract
AbstractSelf-weight transmission under friction inequality in gravitating loose earth can be analyzed under the framework of continuum theory. This chapter concentrates on load transmission of prismatic sand heaps in loose conditions. Nadai’s idealization of a gravitating loose earth was adopted to solve for the closed-form stress field solution. The solution shows good agreement with the experimental data. This chapter reviews this ongoing research and presents graphic illustrations and interpretations. A sand heap is found to be stable on a threshold of resistance, indicating that the load-bearing structure of a sand heap can be promptly destabilized by a marginal disturbance.KeywordsFriction AngleCentral PlanePartial Derivative EquationMajor Principal StressStress ClosureThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
