基于FLAC^(3D)的不同埋深地应力场分布特征的研究

Study on Distribution Characteristics of Different Depth of Ground Stress Field Based on FLAC^(3D)

针对含断层的岩层,选取10个不同埋深的地层进行相应的计算及分析,通过对FLAC3D计算模型施加自重力和在模型边界施加切向和法向力的方法,来模拟岩体在自重和缺陷结构相互作用下产生的区域内地应力,得到埋深是决定区域内垂直应力的主控因素,并分析了断层构造及埋深对地层主应力的影响。

For rock containing faults, depths of selecting 10 different formations corresponding calculation and analysis, by applying a self-gravity to FLAC^3D model and applying tangential anti normal force method to sitar, late rock in weight anti defects in the model boundary regional interior structure interaction under stress,is to determine the main factors that give depth vertical stresses in the region,analyze the structure and depth of the impact of fault on the formation of the principal stresses.
