逆断层活化范围变化规律数值模拟

Numerical Simulation of Change Laws in Reverse Fault Activating Scope

摘要: 为了探索逆断层活化范围的变化规律，基于FLAC^3D数值模拟方法，建立逆断层活化范围分析模型。通过监测断层的相对位移量和切向应力与法向应力的比值，来分析逆断层活化响应范围的变化规律。得出煤层埋藏深度、煤层开采高度、断层倾角均对断层活化响应范围造成影响，并且逆断层活化范围随煤层埋深、煤层采高和断层倾角的增加而增大。

Abstract: In order to explore the changing laws of reverse fault activating scope, based on the way of FLAC^3Dnumerical simulation, the analysis model of activation range was established. The range of activating reverse fault was analyzed with the relative displacement and the ratio of normal stress and tangential stress in reverse fault. The range were impacted by the mining depth, mining height, fault dip and fault properties. The activation range of fault is increased with the increase of mining depth, mining height and fault dip.
