    BIOLOGICAL EFFECTS ON ENGINEERING GEOLOGICAL PROPERTIES OF SEABED SEDIMENTS

    • 摘要: 底栖穴居动物是河口潮滩生态系统的重要组成部分,它对沉积物的二次改造作用非常重要。本文以黄河三角洲钓 口区潮滩为研究对象,研究了不同生物密度对沉积物工程地质特征的改造,包括滩面形态、沉积物强度、以及沉积物颗粒大小 的改变。在此基础上探讨了生物活动与滩面凹坑,沉积物强度非均匀性以及研究区浮泥之间的关系。

       

      Abstract: The near-shore and estuarine environments, which are commonly dominated by benthic species, are important factors in changing the sedimentary conditions. This paper presents effects of estuarine species on sediment geological properties including morphologic, penetration strength and grain size of sediments in Diaokou area around the delta of the Yellow River. The relationships among biological effects, the formation of depression, strength heterogeneity of sediment and distribution of mud are also discussed.
