摘　　要：德商高速公路鄄城黄河大桥桥位区地震活动频繁,地基饱水的粉、细砂层发育。通过场地液化势宏观和微观判别,对桥区地基进行了液化综合评判,计算了桥区地基液化指数,划分了液化等级;指出砂土液化必须采用多种方法进行综合判别,以提高液化判别的可靠性。Within the site of Juancheng Yellow River Crossing Bridge on Dezhou-Shangqiu highway, the earthquake activity is frequent and there develop saturated silty and fine sand layers. By means of macro and micro judgement on the liquefaction tendency of the site, the article makes comprehensive estimations on the ground liquefaction of the site of the bridge, makes calculations of the ground liquefaction indexes and makes suggestions of the liquefaction levels. The article recommends that multiple methods should be used to estimate on the liquefaction of the sandy soils so as to improve the reliability of the liquefaction judgement.
