【摘要】 本文在对某矿山岩质边坡进行了大量的岩体结构面现场调查的基础上,根据所取得的岩体结构面特征参数进行几何学参数的统计分析,得到了节理裂隙分布统计图、粗糙度统计直方图等,再利用岩体节理分析软件模拟得出结构面赤平极射投影极点密度等值线图及影响岩体稳定的优势结构面产状分布图,在对以上结果进行分析得出结构面的特征参数分布图与现场实际情况较为吻合,赤平极射投影法能对岩体在结构面稳定性进行定量的图解分析,而优势结构面稳定性分析,可为岩体强度和工程岩体稳定性评价提供依据。更多还原

【Abstract】 This paper presents the results of geotechnical investigation of the rock mass discontinuities of a copper ore district in China.Firstly,geometrical parameters of rock mass discontinuities were anal yzed to obtain the distribution pattern of joint fissure and histogram of roughness.Secondly,by the hel p of software,the density contour of polar stereographic projection was plotted,and the attitude of pref erred structural plane which related to rock mass stability was determined.Finally,a comparison of stat istical results and physical measurements was made which has shown a good consistency.The results o f the discontinuity data were interpreted with the application of stereographic projection techniques for quantify the stability of rock mass.And combined with analysis of preferred structural plane,the streng th and stability of engineering rock mass could be identified.更多还原
