扫码查看
利用大型通用有限元软件ABAQUS,建立单桩负摩阻力数值计算模型,着重研究地下水位下降时软弱地基中摩擦型单桩的负摩阻力性状.同时,分析了地下水位下降对摩擦型单桩负摩阻力、中性点位置、桩周土沉降、桩顶沉降发展规律的影响.上述研究的结论,对桩基础设计具有一定的借鉴意义.
numerical analysis of negative friction and settlement of single pile induced by ground water falling
The numerical calculation model for the negative friction resistance of a single pile is established using the large-scale general finite element software ABAQUS.Emphasis is placed on studying the negative friction resistance of a frictional single pile in weak founda-tions when there is a drop in groundwater levels.Additionally,an analysis is conducted on the influence of groundwater level drops on the development pattern of negative friction resistance,neutral point position,soil settlement around the pile,and pile tip settlement.The find-ings from this research have significant implications for designing pile foundations.
