摘要
岩体的结构特征是决定工程稳定性的重要因素.对岩体结构特征的刻画,已成为工程稳定性分析中不可缺少的手段与依据.根据岩体的结构特征,从三维构模的角度上,将层状岩体划分成连续型非褶皱岩体、断裂型非褶皱岩体与褶皱型岩体3种基本类型的结构单元.在此基础上,形成分别适用于3种类型结构单元的柱体构模方法、表面构模方法与断面构模方法;对应3种基本结构单元,建立3种空间数据模型,即:柱体模型、TIN面模型与断面模型.并通过模型实例验证了构模方法与空间数据模型的可行性.
The structure characteristic of rock-mass is an important factor for the engineering stability. And description of structure characteristics has become one absolutely necessary tool and base for evaluation of the engineering stability. According to the structure characteristics, on the view of 3D modeling, layered rock-mass was divided into three basic types of structure element: continuous rock-mass (non-folded), fault rock-mass (non-folded) and fold rock-mass. Accordingly, three kinds of modeling methods: Pillar modeling method, surface modeling method and section modeling method were developed. And three kinds of spatial data model: Pillar model, TIN face model and section model, were built up for these three kinds of rock-mass.
