| 摘 要： | 螺丝湾电站引水隧洞总长５０４１ ｍ ，沿线主要为二迭系玄武岩，岩石坚硬。但断层、挤压破碎带及裂隙发育，据开挖揭露出的大小断层共５０ 条，挤压破碎带１８３ 条，隧洞经过这些地段，对围岩稳定有一定影响。总的说开挖前对地层岩性、地质构造、工程地质及水文地质条件的评价与开挖后的情况基本一致

| Abstract: | The power tunnel of the Luosiwan hydropower station, 5,041m long, is located in an area that consists mainly of Permian hard basalt, and is however characterized by developed faults, compressive fractured zones and fissures. Altogether 50 large and small faults and 183 compressive fractured zones were exposed during excavation. The rock excavation for the tunnel had certain impact on its surrounding rocks. The assessment of strata rock properties, geological structure, engineering geology and hydrogeology made before excavation is in line with that exposed after excavation. |
