连云港滨海相软土工程特性

Characteristic of Marine Soft Soil in Lianyungang

根据江苏连云港地区大量的工程地质勘察资料 ,就该区软土层的成因类型、物理力学特性、室内试验问题、现场原位测试 ,特别是力学指标的确定进行了深入的探讨和分析 ,结果表明 :室内试验确定连云港地区软土力学指标误差大 ,有些指标与实际误差在 2倍以上 ,常难以把握。用十字板。

Based on the large quantities of geological survey materials of Lianyungang area,a series of problems about the soft soil are studied,such as the type of formation cause,the physical characteristics ,the indoor experiment,the local experiment and the confirmation of mechanical indexes in particular.The result shows,there are some errors in confirming the mechanical indexes of soft soil by indoor experiment,somtimes the value confirmed by indoor experiment is twice as big as that confirmed by local experiment,which is difficult to handle.Vane test or CPT is suggested to confirm the mechanical indexes of soft soil.
