滨海互层土工程特性试验研究与探讨

以天津滨海新区黏性土与粉土互层土为研究对象,通过开展液塑限试验、三轴剪切试验、渗透试验、固结试验、无侧限抗压强度试验,分析得出研究土层黏粒含量相对较多,属于高压缩性土;水平渗透系数与垂直渗透系数相差2个数量级;提出了合理确定滨海互层土工程参数的建议。

Based on the liquid-plastic limit test,triaxial shear test,permeability test,consolidation test and unconfined compressive strength test,it is concluded that the clay content of the soil layer of Binhai New Area in Tianjin is relatively high.The horizontal permeability coefficient differs from the vertical permeability coefficient by two orders of magnitude,and the reasonable determination of engineering parameters of coastal interbedded soil is suggested.
