背水坡地基处理对桩基框架结构堤防的影响
发布时间：2018-08-16 14:53
【摘要】：在深厚软土地基条件下,背水坡闭气土方填筑对桩基框架结构堤防的受力、变形将产生较大影响。为分析上述影响的规律性,结合温州市某海堤工程实例,以实际工况为条件,采用Midas NX有限元软件,分析了板桩、密排灌注桩及搅拌桩地基处理后桩基框架结构堤防的变形特点。结果表明:水泥搅拌桩地基处理效果最好。进一步分析了不同搅拌桩桩长和桩间距的处理效果,探讨了搅拌桩的最优配置。
[Abstract]:Under the condition of deep soft soil foundation, the stress and deformation of the pile foundation frame structure embankment will be greatly affected by the closed earth filling on the back water slope. In order to analyze the regularity of the above effects, combined with an example of a seawall project in Wenzhou City, the sheet pile was analyzed by using Midas NX finite element software under actual working conditions. Deformation characteristics of embankment of frame structure of pile foundation after treatment of compacted cast-in-place pile and mixing pile foundation. The results show that the treatment effect of cement mixing pile foundation is the best. Furthermore, the treatment effect of different mixing pile length and pile spacing is analyzed, and the optimal arrangement of mixing pile is discussed.
