某造船基地吹填场地真空预压及深层地基处理土体的扫描电镜SEM分析
摘要:结合水泥土搅拌法的加固原理,通过对某造船基地吹填场地原状土和处理后水泥土微观结构利用扫描电镜(SEM)对比分析,从微观角度描述和分析了不同情况下(包括原状土土质、深度、固化材料种类等)使用水泥土搅拌法进行深层地基加固的优劣,有针对性地提出了提高水泥土搅拌桩强度的建议,从而指导实际工程的进行。
Abstract:Combined with the reinforcement principle of soil-cement mixing method,SEM was used to analyze the microstructure of undisturbed soil and treated soil in a shipbuilding base hydraulic reclamation area.From the microscopic point of view,this paper describes and analyzes the advantages and disadvantages of using the method of cement soil mixing to reinforce the deep foundation of the site under different conditions(including the original soil,the depth,the type of curing material,etc).Some suggestions are put forward to improve the strength of cement soil mixing pile,and so as to guide the actual project.
