摘　　要：结构面连通性的判别是岩体工程中的一个应用难题,究其原因是其理论基础欠缺,因此,开展其原理与判别方法研究具有重要理论意义。运用空间几何和向量等数学方法分析工程岩体空间上任意两结构面的共面条件;基于结构面的地质特征论证两结构面的相似条件;给出结构面连通性判别条件,推导结构面相关度计算公式,从而形成一套完整的结构面连通性原理与判别方法理论体系。结合广西铜坑矿锌多金属矿体开拓巷道结构面调查数据,开展连通性原理与判别方法的应用验证研究。应用表明:利用探讨的原理与方法,可以快速有效地判断工程中两结构面的连通性。研究成果可为其他岩体工程中结构面连通性的判断提供理论依据。The distinguishing of connectivity of structural planes is an applicative problem in rock mass engineering because of the lack of the relevant theoretical basis. So, it has an important theoretical meaning that the connectivity principle and distinguishing method of the structural planes is studied. Firstly, the coplanarity conditions of any two structural planes in engineering rock mass space are analyzed by using the mathematical methods such as space geometry and vector. Secondly, the similarity conditions between any two structural planes are demonstrated on the basis of the geological features. Thirdly, the distinguishing conditions of connection of the structural planes are given, and formulas for the correlativity of the structural planes are put forward. So, a complete set of theoretical system of the connectivity principle and the distinguishing method of the structural planes is established. Finally, combining the survey data of Zn-polymetallic ore body in the roadway of Tongkeng Mine in Guangxi Province, the application effect of the above theory is studied. The results show the connectivity of the structural planes can be judged quickly and effectively using the proposed principle and method. This study may provide a theory basis for judging the connectivity of the structural planes in other rock mass projects.
