摘要
为了处理滨海软土路基,使其承载力和压缩模量达到设计要求,结合现场工程地质条件,采用先抛填块石至一定标高,再采用强夯工艺对抛石进行处理,取得了良好的处理效果。通过对处理后地基所做的荷载试验、钻芯检测和沉降观测分析,路基经强夯处理后,承载力及变形均达到设计要求。强夯技术因设备简单,施工方便,经济易行,适应于处理抛石填筑后的埋深较浅的滨海软土地基。
When deal with the coastal silt foundation, according to the geologic and actual condition of the project, dynamic consoli-dation method on rubble foundation is qualified as practical. After dynamic compaction , the result of roadbed load test, drilled core test and settlement observation showed that the bearing capacity and settlement control of the roadbed can meet the design require-ments. The result of the treatment is good. For dynamic dompaction is simple in equipment usag econvenient in construction and economical , it can be widely used in coastal silt riprapped foundation treatment.
