为了进一步探讨土钉支护的作用机理、受力特点,采用Flac3D模拟土钉支护基坑开挖与支护的施工过程,并对土钉、土体在开挖过程中的受力性能进行了模拟和分析。通过对土钉支护基坑模型的土体应力、应力路径和土钉内力分布等力学参数的分析,能更加全面地认识其在开挖阶段的工作性能,对其设计和施工提出了有益的建议。
為瞭進一步探討土釘支護的作用機理、受力特點,採用Flac3D模擬土釘支護基坑開挖與支護的施工過程,併對土釘、土體在開挖過程中的受力性能進行瞭模擬和分析。通過對土釘支護基坑模型的土體應力、應力路徑和土釘內力分佈等力學參數的分析,能更加全麵地認識其在開挖階段的工作性能,對其設計和施工提齣瞭有益的建議。

In order to investigate the mechanism of soil nailing and mechanical characteristics ,a numerical model considering the working procedure of excavation and supporting was established by Flac3D,and the mechanical performance of the soil and soil nails during the excavation process was simulated and analyzed. By analyzing the stress of soil,stress path and the force distribution of soil nailing in soil nailing model,the behaviors of soil-nailed structures in construction phase are further investigated and it will be given for references to the future design and construction on soil nailing walls.
