| 摘 要： | 受机械性能限制，振冲器无法穿过深厚漂卵砾石地层，对此类地基无法用振冲技术进行
处理。采用冲击钻机造孔后引孔振冲工艺克服了振冲器局限性，成功地进行了多个水电站的基础
处理，实现了振冲技术在深厚漂砂卵石复杂地层中应用，拓展了振冲技术的应用范围，实现了新
的突破。

| Abstract: | Under the limitation of the mechanical performance,the vibroflotation device cannot cross the deep-thick cobble and gravel strata,and then this kind of foundation cannot be treated with the vibroflotation technology.Through the adoption of the vibroflotation technology with bore-forming by percussion drill,the limitation of the vibroflotation device is broken up and the foundation treatments for several hydropower stations are successfully carried out with this technology,i.e.not only the application of the... |
