摘要
地基承载力深度修正原理是基础底面以上两侧的超载能限制地基土的破坏变形,从而提高地基极限承载力,因此上部结构施工前的回填土可以算在深度修正范围内,而不需要考虑回填土是否压密固结。土体长期压密对承载力的提高是由于土的内摩阻力的提高,这是两个不同的影响地基土承载力的因素。
The contribution of the depth modification to the subgrade bearing capacity is that the overload around the foundation above the underside limits the subgrade soil deformation. So that the backfilled soil before the main structure constructed can be counted, no matter whether the backfilled soil is compacted and solidified. Long term compaction and consolidation of the soil can raise the subgrade beating capacity is because of the internal fiction force raised, these are two different factors that effect the bearing capacity.
