黄河冲积平原粉土地基载荷试验研究

Study of Plate Loading Test of Silt Foundation in Alluvial Plains of Yellow River

黄河冲积平原地区粉土地层具有特殊的工程地质特性,作为天然地基持力层时,需要准确了解承载力变化规律及变形特性。本文通过现场的浅层平板载荷试验,对粉土层地基的变形特征进行了讨论,并结合室内土工试验和现场原位测试综合比较分析,确定了承载力特征值。本文的研究对相似工程有一定的参考意义。

The silt layer in alluvial plains of Yellow River has special geological character as natural foundation supporting course,so the bearing capacity and deformation law of this layer need to be learned.Through plate loading test,the deformation law of silt foundation was discussed,and combined with soil mechanics test in laboratory and in-situ test,the characteristic value of bearing capacity was determined.
