| 摘 要： | 皂市水利枢纽右岸导流洞长428 m,穿越泥盆系及志流系地层,洞室走向与地层走向近于正交。隧洞进出口条件较差,下游段主要在页岩及粉砂岩中通过。开挖前,根据地表露头及勘探资料,对洞室围岩质量进行了预测。开挖过程中,隧洞进出口及其附近洞室段先后出现险情,在调整施工方法和采取加固措施后得以顺利贯通。

| Abstract: | The diversion tunnel of the Zaoshi hydropower project, 428m long, traverses the Devonian and the Silurian layer. The geological condition of the inlet and the outlet of the tunnel is not ideal for the excavation and the stability. The surrounding rock quality has been predicted before the construction according to groundsurface geology and exploration information. During the excavation, the grand deformation was found at the inlet, the outlet and nearby. The reinforcement measures have been used for the continuation of excavation. |
