摘要
黄骅港地区海底表层存在一层饱和软土,对工程结构的设计及稳定性分析有重要影响。为准确确定该层土的十字板剪切指标,本文引入灰色关联分析方法,以黄骅港散货港区矿石码头工程数据为例,通过计算该土层十字板强度指标与各主要物理性指标的灰色关联度,可知十字板强度值与天然重度指标关系最为密切,且地基处理的不均匀性对十字板强度影响较大。
A saturated soft soil layer exists on the seabed surface of Huanghua Port, which plays an important role in the design and stability analysis of marine structure. Grey correlation analysis is used to determine vane shear index of the above soil layer. Mineral Terminal project of Huanghua bulk cargo harbor is taken as an example to calculate the grey correlation degrees between vane shear strength index of the above soil layer and other major physical indices. The calculation results show the closest relation between vane shear strength index and natural gravity Index as well as the unevenness of foundation improvement that has a great effect on vane shear strength index.
