淤土地基大直径灌注桩水平承载特性M法计算研究

摘要

Combined with the conditions of silt land base in Sanyo Harbor tidal gates engineering,we analyzed the effects of horizontal load bearing characteristics of large diameter pile. For this propose ,we used M numerical calculation method to study horizontal load bearing characteristics. By comparing the numerical simulation with the measured datam,the fitting degree is good. It shows that using M method to analyze horizontal load bearing capacity is reasonable. The study provides reference value for further exploit of M method.%结合淤泥土地基中的三洋港挡潮闸工程，研究大直径灌注桩水平承载特性的效果，在现场进行水平静载荷试验。利用M法数值计算对水平承载特性进行研究，并与现场试验结果进行对比分析，结果表明，现场实测数据和数值模拟的拟合程度较好，说明M法在桩基水平承载能力研究方面具有合理性，为进一步利用M法研究桩体水平承载力提供了一定的参考价值。
