| 摘 要： | 本文将多重分形谱引入到土微观结构分形研究中,对天津市滨海新区三个不同地点海积软土原状样及不同固结压力后土中孔隙的多重分形特征进行研究,从多重分形的角度对孔隙的不均匀性进行定量描述,并建立孔隙多重分形谱各特征参数与荷载之间的关系.结果表明三个地点的海积软土孔隙多重分形特征存在差异.

| Abstract: | By introducing a multi-fractal chart to a study of the marine soil microstructure, this paper examines the multi-fractal characteristics of pores in the undisturbed soils and marine soft soils under different pressures of three regions in the new developing coastal region of Tianjin. From the point of view of multi-fractal, the asymmetrical properties of porse are described quantitatively. Relationship between characteristic parameters of porous multi-fractal chart and stress are established. The results indicate that multi-fractal characteristics of pores of marine soft soil are different from one to another among the three regions. |
