基于对水泥土引孔桩工艺与常规工艺的现场静载试验研究,以现有的试验数据为基础,采用有限元分析工具ABAQUS对水泥土引孔桩和直接压桩进行有限元模拟,对单桩承载力以及桩土之间共同工作特性和相互作用进行数值计算。分析结果表明,通过合理的参数设置和接触模拟,计算与试验所得的Q-s曲线吻合良好,水泥土引孔桩的承载力大于相同尺寸的直接静压桩,其承载力提高机理是桩侧摩阻力的提高。分析结果可为水泥土引孔桩的进一步发展提供借鉴。

On the basis of on-site static loading test of guiding hole technology using cement-soil pile and the normal technology, the law of load transfer and the interactive behavior of the pile and soil of the guiding hole pile and the pile is analyzed using the normal technology by the finite element analytical software ABAQUS. The result of analysis shows Q-s curve of test and those of the simulation are consistent with reasonable parameters setting and contact simulation. Besides, the loading capability of the guiding hole pile is bigger than that of the pile using the normal technology in the same size. The mechanism of the improvement of loading capacity is due to the improvement of side soil resistance. Therefore, the analytical conclusions could give help to the further development of guiding hole technology using cement-soil pile.
