摘要
通过工程实例探讨了孔内深层强夯法(DDC)在大厚度湿陷性黄土地区的应用,该法既可消除地基土湿陷性,又能大幅提高地基承载力,处理地基的效果显著,且用料广泛,可就地取材,节约耕地,保护生态,降低工程造价,具有广泛的适用性和良好的应用前景。
By means of engineering cases, the application of down - hole dynamic compaction （ DDC method） in thick - bedded collapsible loess area was discussed. This method, not only to eliminate collapsibility of founda-tion soil, but also to greatly improve its bearing capacity so that obvious results of treating foundation can gained and raw materials can widely used, has the extensive applicability and good application foreground that can use local materials, save cultivated land, and protect eco -environment so as to reduce the engineering cost.
