| 摘 要： | 公伯峡水电站枢纽建筑物地段地质条件复杂，存在三大不同成因类型的岩石，河西系与祁吕系新、老两期构造迭加，古风化岩与现代风化岩工程地质特性差异明显。经勘察评价，公伯峡工程区域稳定条件好，地震活动较弱，工程地质条件良好，虽无重大地质问题，但存在开挖边坡卸荷松弛速度快及右岸导流洞成洞条件差等问题。

| Abstract: | The geological conditions of Gongboxia Hydropower Station is complicated, with the existence of three difference genetic types of rock. The formation of Hexi system is superposed with the old and new Qi-lu system, and the engineering geological characteristics of ancient weathered rock. By exploration, the region of Gongboxia Hydropower Station is stable, with weak earthquake activities and good geological conditions. Although it has no big geological problems, there still exist quick speed of relaxed rock of excavated slope and poor formation of diversion at the right bank. |
