Microstructure Features for Dredger Fill by Different Solidified Technologies
摘要
Abstract
With the dredger fill in Tianjin Binhai New Area as study object,the mineral composition is identified by X-ray diffraction approach,and the microstructure is studied by scanning electronic microscope (SEM) along with quantificational analysis of the microstructure on the basis of WD-5 picture processing system.And then the changing of evaluation indicators by two different reinforcement approaches,such as the size of structure element and pore,abundance,and directional frequency are discussed.The conclusion indicates that after water drainage treatment,the porosity becomes smaller,the dispersed structural elements of soil become agglomerated elements,displaying a variety of oblate.Simultaneously,the pores in the soil diminishe and lose balance,and the directing property becomes indistinct.Consolidation degree of soil becomes higher.关键词
