深层搅拌桩地基处理的XRDX射线衍射分析
摘要:结合水泥土搅拌法的加固原理,对某造船吹填场地原状土和处理后水泥土微观结构利用X射线衍射(XRD)进行对比分析,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效果,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优化改进。
Abstract:This study combined with the cement-soil mixing method,the X-ray diffraction(XRD) analysis of the undisturbed soil and the treated cement-soil microstructure in a shipbuilding reclamation site is performed to describe and analyze different conditions from a microscopic perspective.Including undisturbed soil,soil,depth,types of solidified materials,etc.Cement-soil mixing method is used to reinforce the deep foundation of the site,and the suggestions improving the strength of the cement-soil mixing pile are specifically proposed to guide the optimization and improvement of the actual project.
