摘　　要：探讨了复合材料桩的成桩机理和施工方法.在工程试桩的基础上,建立复合材料桩承载性能的数学分析模型.利用实测试桩资料,通过数值分析,研究该类桩的承载机理和特性.在弹性条件下对混凝土芯复合材料桩进行受压性能分析,并在相同位移条件下将其与相同条件的水泥土搅拌桩进行对比.计算结果显示:复合材料桩的承载性能优良,对土体横向、纵向影响范围大,受力分布均匀,并具有刚性桩的受力特征.研究表明:复合材料桩承载力高、沉降量小、施工方便、造价低廉,在地基工程中具有广泛的应用价值.Fomating pile mechanism and construction method of composite pile a re explored in the paper. Math mode of load bearing capacity of composite pile i s built based on the static load test .Load bearing mechanism and characteristic of composite pile are researched based on the numerical analysis and compared w ith cement-soil pile under the same conditions .The results show that composit e piles have good load capacity and load bearing characteristics of concrete pil e. It is proved that composite pile has many advantages such as simple construct ion method, high capacity, small settlement, low costs and extensive adapt ability in ground engineering.
