摘要
通过具体工程实例,对大面积堆载作用下软土地基变形进行了详细计算与分析,并与复合地基处理后的地基变形量进行了对比。分析认为大面积堆载对地基变形影响深度较大,超出了常规荷载作用下的影响深度;与复合地基相比,大面积堆载地基变形量要多出25倍左右;大面积堆载影响深度范围内,要考虑负摩阻力作用。
Based on the engineering examples, the detailed calculation and analysis on the role of foundation deformation with large -scale preloading were carried out and compared with the deforma- tion of composite foundation treatment. The results showed that the influence depth of foundation de- formation under the large - scale preloading was large, and exceed the influence depth of conventional load depth; compared with the composite foundation, the deformation of foundation under large - scale preloading was 25 times more than composite foundation; the negative skin friction should be considered in influence depth range under large - scale preloading.
