摘要
在新近杂填土上建厂 ,因杂填土松散、厚度大、基岩埋深大 ,若采用基岩作天然地基即用人工挖孔桩或机械成孔灌注桩 ,则很不经济 ,施工也存在安全隐患 ,易坍孔 ,且工期长。经过比较 ,采用灰土碎石挤密桩对杂填土进行处理后 ,作复合地基 ,施工易于操作并极大的缩短了工期 ,取得了良好的效果。
For the loose soil, high thickness and deep bedrock in the miscellaneous fill, the factories are non-economic to be constructed on the newly miscellaneous fill providing the foundation rocks are chose to the natural foundation, i.e. using artificial hole digging piles or mechanical hole-making poured piles, while the hazards exist in potential, the holes are inclinable to collapse, and the construction is long in period. Comparatively, the vibrated compaction piles of spodosol rocks are applied to deal with the miscellaneous fill, which may be used as the compound foundation. As a result, the construction is liable to be carried out and its period is shorten greatly, and arrives at the good effect.
