# 高边坡岩体结构面发育特征及其对边坡稳定性的影响Developmental Characteristics of Rock Mass Structure and Its Effect on Slope Stability in High Slope

Abstract: The development and distribution of structural facies in rock mass have an important influence on the stability of slope. Based on the example of high slope engineering in opencast mine, the structural surface of slope is measured and analyzed statistically. The preliminary qualitative evaluation of slope is made, which provides relevant reference for post-level quantitative evaluation of slope stability and analysis method. In this paper, the lateral line method is used to obtain the basic data of the structural surface of the rock mass. The pole plot, the equal density map and the joint roses are drawn and analyzed to obtain the dominant structural plane by Lizheng software. Using the matlab software to analyze the basic data, the corresponding probability distribution histogram and fitting curve are obtained, which is in good agreement with the probability model. The results show that the stability of the structural slope is relatively small and the slope is basically stable.
