Analysis on Stress Field Features and Their Influence Factors of the Loaded Rock with Fissures

通过数值模拟的方法 ,应用RFPA2D软件分析了含裂纹岩石受载后的应力场分布特征 ,用定义的应力集中系数来分析由于裂纹的影响而产生的应力场强度 。

Numerical simulation method is used in this paper.RFPA 2D software is applied to analyze the stress field distribution features of the loaded rock with fissures.Stress concentration factor is defined to analyze stress field intensity resulted from the fissure influence.The effect of these influence factors,such as fissure length,its mechanical parameters, on distribution of stress field is studied.
