摘　　要：通过引入应力综合结构势来分析花岗岩砂质粘性土的结构性。以深圳宝安区新龙园二期工程施工工地的砂质粘性土为例,对土样进行原状、饱和、重塑状态下的压缩试验,得到结构性参数曲线,得出含水量、干密度及压力的变化对砂质粘性土的结构性有显著影响的结论。Through introducing the comprehensive structure potential parameter of stress, the paper analyzes the structural characters of sandy clay. According to the samples of the sandy clay of the construction location of New Longyuan project Ⅱ in Baoan district, Shenzhen, the paper made the confined compression tests in their intact, saturated and remoulded conditions to obtain the curves of the structural parameter, and inspected how the water content, dry density and pressure had an effect on the structural characters of the sandy clay. And a conclusion is drawn that the change of the water content, the dry density and the pressure have remarkable effect on the structural characters of the sandy clay.
