| 摘 要： | 粉煤灰海水湿排造陆是沿海地区粉煤灰利用的主要途径之一。但造陆以后属于软土地基，不能直接利用，必须对其进行地基处理，处理效果如何，需进行评价。本文研究强夯处理在青岛沿海粉煤灰排放区的应用，并采用载荷试验、圆锥动力触探试验、室内实验等多种方法对强夯处理效果进行检测。检测结果表明，强夯处理后粉煤灰地基土能够达到设计的150kPa要求，为海水湿排粉煤灰造陆地基处理方法的应用和处理效果检测提供了借鉴。

| Abstract: | Discharging wet flyash into sea for reclamation is one of the main ways for utilizing flyash in the coastal areas. However, the flyash ground has been usually very soft and loose, and can be used as building foundation after it has been treated properly and the treatment results have been evaluated. In this paper, applications of dynamic compaction （DC） are studied in the flyash discharging regions along the Qingdao Coast. Various methods are used to detect the DC results, e. g. , plate bearing test （PLT）, dy namic penetration test （DPT） and in-lab tests. Test results show that the bearing capac ity of DC-treated flyash ground could meet the design requirement for 150 kPa. This paper can serve as a reference for the applications of the wet flyash in the reclamation and the ground treatment result detection. |
