【摘要】 结合某基坑土钉支护实例,采用FLAC3D对土钉在开挖过程中的受力性能进行了模拟和分析。根据土钉支护结构的开挖、支护情况,研究了土钉的内力分布规律,得到了基坑在开挖过程中土钉的轴力、剪力变化规律。利用试验数据对模拟结果进行了验证,模拟结果与试测值基本吻合,研究成果近一步解释了钉土的相互作用机理。更多还原

【Abstract】 In this paper,the authors analyze internal forces of a soil nail system during excavation using FLAC3D.Based on excavation and supporting conditions of soil nail structures,the internal force distribution patterns weredetermined.In addition,axial force and shear stress of the soil nail were evaluated.The experimental data matchwell with the computational results from FLAC3D,which allows one to gain a better understanding of interaction ofnails and soil.更多还原
