The Influence of Lateral Fill on Foundation Bearing Capacity of High-Stacked Culverts
To find the improved effect on the foundation bearing capacity of lateral fill,combining with the stress characteristics of the foundation soil,the soil force was analyzed.One element of the soil body was taken as the research object,according to the force equilibrium condition of the element of soil,the ultimate bearing capacity could be obtained by calculating torque of one point.The Prandtl and Prandti-Reissner foundation ultimate bearing capacity formulas were deduced and contrasted.The results showed that the lateral fill could improve the bearing capacity of the culverts foundation when the settlement of the culverts foundation satisfied the design request.
