预应力管桩复合地基处理应用技术问题的探讨

Technical Issues Discussion on Application of Prestressed Concrete Pipe Pile on Composite Foundation Treatment

通过分析预应力管桩复合地基处理桥台、通道和箱涵与路基间的过渡段的资料结合处理通道和箱涵结构物基础产生的问题,研究预应力管桩复合地基的适用范围,并根据现场管桩施工试验资料,探讨管桩复合地基的设计思路、管桩施工的收锤标准以及检测方法。

Through analysis on data of transitional section between embankment and abutment, underpass or box culvert treated with prestressed pipe pile composite foundation, considering treatment to disease of foundation of underpasses or box culverts, the scope of application of the prestressed pipe pile composite foundation has been studied, and the design ideas of pipe pile composite foundation, collecting hammer standard and detecting meth- od of pipe pile construction have been discussed according to the experimental data of site pipe pile construction.
