江苏连云港地区滨海相软土地质特性研究

Study on the Geological Characteristics of Soft Soil in Littoral Facies, Lianyungang, Jiangsu

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、CPT方法有较好的效果。

Based on a great number of investigation information on engineering geology, the authors make discussions and analyses on the genetic types, physical and mechanical characteristics, inside experiment, site test of original locality and the determination of mechanical criteria in particular in the studied region. The results demonstrate that the inside experiment makes a big error in determining the mechanical criteria of the soft soil in the region of Lianyungang and the error for some of the criteria with the reality is over twice, the handling is usually difficult. The effects produced by cross panel and CPT method are better.
