在地下洞室的变形和稳定分析之前,确定相似结构的岩体是十分必要的工作。通过对蒲石河抽水蓄能电站地下厂房区探洞中结构面的调查、资料分析,利用S. M. Miller的岩体结构分区原理对电站厂房探洞进行了结构分区,从而可以对各结构均质区进行结构面产状、密度等进行数值模拟,建立三维网络数值模型,进一步对地下厂房区的结构面的发育特征进行模拟、研究,并对洞室分类有一定的指导作用。
Before the deformation and stability analysis of underground caverns, it is very necessary to determine the similar structure of rock mass. Through the investigation and data analysis of the structural plane in the underground powerhouse of Pushihe Pumped Storage Power Station, the structural division of the exploration caverns of the powerhouse is carried out by using the structure principle of rock mass structure of SM Miller so that the homogeneous regions of each structure can be carried out The surface shape and the density of structural surface are numerically simulated, the numerical model of three-dimensional network is established, and the developmental features of the structural surface in the underground workshop area are further simulated and studied, and the classification of the cavern is instructive.
