FLAC^(3D)对土钉支护机理的数值模拟分析

Data Simulation Analysis of Support Principle to Soil Nail by FLAC3D

结合工程实例,建立了土钉支护稳定性分析模型,选用FLAC3D进行数值模拟。通过模拟,揭示了无支护开挖与支护开挖过程中应力场和应变场的变化规律,进一步研究了土钉支护的作用机理和支护性能。数值模拟结论可以为支护设计与施工提供理论依据及参考设计值。

With the example of construction to establish analysis modle of soil nail support stability, and choose the FLAC^3D to do the data stimulation. Changing rules of stress field and strain field in nonsupport excavation and support excavation are revealed by the stimulation. To further research the soil nail support principle and support capability. Data stimulation conclusion can supply the theory and reference designing data for support design and construction.
