| 摘 要： | 德商高速公路（河南范县段）位于豫东北黄河泛流冲积平原，该区地震活动频繁，地基饱水的粉、细砂层较发育。根据《建筑抗震设计规范》GB50011-2001的标准，通过标准贯入试验分析了路基在埋深15m内的地基具有发生砂土液化的可能性，计算了液化指数，划分了液化等级，并对路基处理提出了具体的建议。

| Abstract: | The research region of Dezhou Shangqiu highway in Fan County is located in the Yellow River flooded area, where earthquakes are frequently active and the ground develops with saturated silt and fine sand beds. According to the Code for Seismic Design of Buildings (GB 50011 2001, Chinese code), analysis is made on the possibility of sand liquefaction of the subgrade in 15m depth by means of standard penetration tests. The liquefaction indexes are calculated, liquefaction grades are determined and concrete liquefaction control measures are recommended in the paper. |
