对于由地质构造面纵横切割的多裂隙岩石块体的稳定分析,块体理论不失为一种有效的分析手段。但是,它在分析过程中仅考虑结构面和开挖面的产状,所以必须根据开挖面的地质素描图才能确定失稳块体的具体位置。因此,在事实上它无法在开挖施工之前就准确预测失稳块体的位置。本文根据地质结构面的空间特性,利用现代科学中的CAD技术,在开挖工程施工之前,我们就设法在计算机上真实地模拟地下工程建筑物及其周围地质环境以及施工演进过程。从而随着开挖施工的演进,逐个寻找出失稳块体的形状、特征和空间位置,进而为工程设计处理提供有效的依据。
For the stability analysis of multi-fractured rock masses cut vertically and horizontally by geological structures, block theory is an effective analytical tool. However, it only considers the occurrence of the structural plane and the excavation surface in the analysis process. Therefore, the specific location of the destabilizing block must be determined based on the geological sketch map of the excavation surface. Therefore, in fact, it cannot accurately predict the position of the destabilizing block before the excavation. In this paper, according to the spatial characteristics of geological structure planes, using CAD technology in modern science, before the construction of excavation works, we managed to simulate the underground engineering buildings and the surrounding geological environment and the construction evolution process on the computer. With the gradual progress of excavation construction, the shapes, characteristics, and spatial locations of the destabilizing blocks are found one by one, which in turn provides an effective basis for the engineering design process.
