黄土地区载体桩成桩质量应用测试研究

摘要

介绍了载体桩工法加固黄土地基的力学机理,结合载体桩在黄土地区应用的工程实例,实测采用载体桩复合地基处理湿陷性黄土和载体桩作为深基础在湿陷性黄土地区的使用效果,分析存在问题的原因并给出了相应的解决方法,结合黄土地区的地质条件指出了该桩的应用范围.%The mechanical mechanism of reinforcing loess ground by ram-compacted piles with bearing base was introduced.Based on the application cases of piles with bearing base in loess area, the effect of treating collapsible loess using the ram-compacted piles as well as the effect of using the ram-compacted piles as deep foundation was tested.At the same time, the reasons and countermeasures of existing problems were proposed.Considering geological conditions in loess area, the application range is given.
