碎石桩与粉煤灰碎石桩复合地基的应用

以太原某小区住宅楼为例，介绍碎石桩与粉煤灰碎石桩联合应用处理地基，可达到既消除液化又提高承载力的双重目的。该场地土属非自重湿陷性黄土，在自重压力与建筑物附加压力的共同作用下受水浸湿时，土体结构将迅速破坏，且强度降低。经分析、计算，采用振动挤密碎石桩与粉煤灰碎石桩联合应用达到了预想的效果。

The application of crushed-stone pile and fly ash crushed-stone pile composite foundation in engineering

Taking a district in Taiyuan as example the composite foundation treatment of crushed stone pile and fly ash crushed stone pile is introduced, the double aims as eliminating liquefaction and enhancing bearing strength are attained. The earth in this engineering is non self weight collapse loess. Under actions of self weight pressure and architecture press the soil body will be destroyed and the intensity will reduced when the soil is soaked by water. Through analysis and calculation the combination application of vibrate compacted crushed stone pile and fly ash crushed stone pile acquired good effects.
