| 摘 要： | 应用块体理论、正交设计方法对三峡地下厂房围岩中裂隙可能构成的随机块体类型、几何特征与稳定进行了分析。所获结果表明：三峡地下厂房的随机块体的虽然稳定性较好，但最大埋深仍可达7-8m，为确保围岩的稳定，系统锚杆的支护长度应大于7m。

| Abstract: | With the block theory and orthogonal design method, the type and geometrical characterstics and stability of random key block in underground power house of the Three Gorges project are analysed. It is showed that the depth of key block in rockmass is possible to have 7-8 m although the stability of random key block in the underground power house is better; and that the embedded length of system bolts shall be greater than 7 m so as to guarantee the stability of rockmass. |
