1、工程地质勘察毕业论文工程地质勘察毕业论文题目:管桩加固湿陷性黄土地基施工设计41工程地质勘察毕业论文摘要本篇论文主要分析了湿陷性黄土的基本机理和地基处理方法。湿陷性黄土泛指饱和的结构不稳定的黄色土,在自重压力或自重压力与附加压力作用下,受水浸湿后,土的结构迅速破坏,发生显著下沉的现象。它的这种特性,会对结构物带来不同程度的危害,使路基及结构物大幅度沉降、折裂、倾斜,严重影响其安全和使用。因此对于湿陷性黄土地基要进行有效地加固处理。通过分析这种特殊地基的基本特性,针对此种地基,采用管桩基础进行加固。从而引入了管桩施工的优点及缺陷以及施工工艺。管桩作为一种新桩型以其桩身质量可靠、承载
2、力高、施工速度快、现场整洁、较为经济等优点越来越得到广泛的应用。但由于管桩的应用时间不长,在研究和应用等方面都还存在着不少亟待解决的问题。简要分析了管桩的承载力以及影响承载力的因素。最后通过一个实例说明了管桩施工的要点和一般步骤,了解到在实际施工过程中施工进度和成本意识的重要性!在这次设计中运用在大学期间所学理论知识对设计进行了整体把握。加深了对理论知识的理解。文中如有不当之处,望指正!关键字:湿陷性黄土、管桩、预应力管桩41工程地质勘察毕业论文AbstractThispaperanalyzesthecollapsibleloessfoundationofthebasicmech
