摘要
为合理评价某水库库岸岩体结构特征及工程整治提供依据,对区内岩体进行了裂隙调查及三维网络模拟研究。研究基于Monte-Carlo模拟方法,由走向玫瑰图、倾向和倾角分布的直方图对裂隙的产状分布特征分别进行了分析,结合裂隙等密度图分析得出了结构面优势产状、用直接法产生随机数并利用计算机模拟得出符合实际的三维裂隙网络图。引入广义计算,讨论了值的变化可能影响库岸岩体在不同方向的稳定性。
In order to evaluate the structural characteristics of reservoir bank rock reasonably and supply the basis for project regulation,the rock crack has been investigated in the area and a 3D network simulation is studied.The study analyzes the distribution characteristics of crack occurrence by trend rose and distribution histograms of dip and dip angle based on the Monte-Carlo simulation method and obtained the dominant texture of occurrence by the crack density map,the random number by direct method and the 3D crack network chart by computer simulation conforming to reality.The study introduces the calculation of RQD2 and discusses the possible influence of its value change on reservoir bank rock stability in different directions.
