摘　　要：介绍了钻孔挤扩支盘桩的工艺、设备、适用条件及经济效益。结合工程实例 ,从挤扩支盘桩的成桩工艺及设备、普通灌注桩与支盘桩承载力对比、静载试验结果几方面进行了详细的论述 ,指出在合适的地质条件下 ,钻孔挤扩支盘桩可以大幅度提高单桩承载力 ,具有很好的经济效益和社会效益。The paper introduces the technology, devices, applicability and economic benefit of broach squeezed piles. Combining with examples of projects, the writer discusses minutely the squeezed pile's technology of forming stakes and its devices, compares it's bearing capacity with that of ordinary perfusion stakes, and introduces the result of static load experiment. In addition, the writer indicates that under appropriate geological conditions, the squeezed piles can greatly improve the single pile's bearing capacity and possesses good economic benefit and social benefit.
