| 摘 要： | 针对树根桩加固隧道软基的试验,采用ABAQUS有限元软件进行数值模拟分析,得到加固前后的地基承载力p-s曲线,在加固前的数值模拟接近实测值,加固后的模拟值略大于实测值,数值模拟能较好的反映现场试验,同时为树根桩在隧道工程中的应用提供参考与理论指导.

| Abstract: | For root pile of soft ground tunnel test,ABAQUS finite element software was used for numerical simulation analysis to get the foundation bearing capacity p-s curves of reinforcement before and after reinfocement.The numerical simulation before reinforcement is close to the measured values,the numerical simulation after reinforcement is slightly larger than the measured values.Numerical simulation can reflect the field test greatly,provide a reference and theoretical guidance for the use of root pile in the ... |
