【摘要】 在分析土钉受力状态的基础上,采用FLAC3D软件研究土钉支护结构的变形。根据土钉支护结构的开挖、支护现状,在大变形条件下,分别对土钉支护结构的整体变形,土钉的拉伸、剪切变形的进行数值研究,并将结果进行对比分析,从而得到了变形的变化规律,结果可为理论研究和相关设计提供一些有价值的参考。更多还原

【Abstract】 The soil nail deformation is investigated by FLAC3D based on the analysis of the behaviors of soil nail during excavation.With consideration of excavating and supporting of soil nail structures,the deformations of the total slope and pull and shear of soil nail under the condition of large deformation are stimulated and analyzed.Simultaneously,some laws about the stress and the displacements distribution are acquired in this model through comparative analysis.The acquired results can be referred by other researches and projects in future.更多还原
