渤海湾西岸沉积物粒度参数特征及其工程性质分析

Analysis of Characters of Granularity Parameters and Engineering Properties of Sediments in Western Coast of Bohai Bay

结合渤海湾西岸的物源供应、沉积环境,在对大港、塘沽、汉沽3个区沉积物的垂向粒度参数(平均粒径、分选系数、偏度、峰度)特征和主要工程性质进行研究的基础上,分析和讨论了3个区粒度特征参数与物理力学性质指标间的关系.结果表明,各区的物源供应、沉积环境、粒度参数、物理性质指标之间有较好的对应性.

Combining provenances supply and sedimentary environment, characters of vertical granularity parameters （ average diameter, coefficient of sorting, skewness and kurtosis ）and its primary engineering properties of sendiments in Dagang district, Tanggu district,and Hangu district of the western coast of Bohai Bay are researched. The relation between granularity characteristic parameters and physical mechanical indexes is analyzed and discussed. The results show that better correspondence is among provenances supply, sedimentary environment, granularity parameters and physical property indexes.
