组合式复合地基在复杂场地高层建筑物中的应用

在自重湿陷性黄土地区的高层建筑中，采用挤土夯扩素混凝土桩结合素土挤密桩法处理地基，增加了桩端阻力及桩摩擦阻力，实现了单桩承载力大大提高的目的，缩短了桩长，节省了费用。

Application of Composite Foundation in High-rise Buildings with the Complex Space

The paper introduces that in areas of high-rise building with the collapsible loess, the soil-compaction expanded concrete piles with the soil-compaction pile composite foundation increases the pile tip resistance and friction resistance of piles, improves greatly the piles＇ bearing capacity and shortens the length of the piles, which saves the cost. In the Xi＇ an ar- ea, this technique was successfully applied in many projects, and achieved success in the miscellaneous fill venues as well.
