摘要
针对滨海粉土的工程特性,在现场钻孔勘探的基础上,进行原位扁铲试验,分析滨海粉土的原位变形和力学特性。结果表明该地基土层大部分为粉土,水平应力指数KD在4.0左右,除表层0~4.0 m波动较大外,土层的静止侧压力系数K0变化趋势与KD类似。因此,本试验结果可为滨海地区的工程建设提供一定的参考。
According to special engineering characteristics of marine silt,dilatometer tests were carried on the base of hole drilling explore,then the deformation and mechanical properties of coastal silt was analyzed.The dilatometer test results show that most of stratums in that area are silt.The horizontal stress index KD is about 4.0 except the depth between 0 and 4.0m.In addition,the tendency of lateral earth pressure coefficient at rest K0 is similar to KD,which is provide a reference for project construction in marine silt area.
