长江口北侧粘性土工程分类探讨

Study on Engineering Classification of Clayey Soils Located at the Estuary North of the Yangtze River

鉴于长江口北侧粘性土物理性质指标与工程特性指标间显著的不吻合性,对其物理性质指标进行了多元统计理论分析,提出现行《公路桥涵地基与基础设计规范》(JTJ024-85)粘性土工程分类存在不尽合理之处的结论,以供参考。

Based on the prominent disagreements between the physical indices and the engineering characteristic indices for the clayey soils located at the estuary north of the Yangtze Rivers,the indices are analyzed by using the multi-statistic theory.The unreasonable contents existed in engineering classification of clayey soils about the Specification for Design of Ground Base and Foundation of Highway Bridges and Culvert are pointed out.
