土工格栅加筋砂土上的偏心受压条形基础研究
摘要:提供了土工格栅加筋砂土上的偏心受压条形基础极限承载力的室内模型试验结果。试验中只使用了一种相对压实密度的砂土和一种土工格栅,基础深度由0变化至B(基础宽度)。基于室内试验结果,提出了一个称为折减系数的经验关系,将偏心受压基础的极限承载力与中心受压基础的极限承载力联系起来。
Abstract:Results are presented for laboratory model tests conducted to determine the ultimate bearing capacity of an eccentrically loaded strip foundation supported by geogrid-reinforced sand. Only one type of sand at one relative density of compaction and one type of geogrid were used for the tests. The depth of the foundation was varied from zero to B (width of foundation). Based on the laboratory test results, an empirical relationship called reduction factor has been suggested that correlates the ratio of the ultimate bearing capacity of an eccentrically loaded foundation with that for a foundation where the load is applied centrally.
