摘要

公伯峡水电站左岸泄洪洞进口边坡高程 1 981 m以下地质情况复杂 ,断层交错 ,对洞脸边坡和左边坡塌方锚固处理很有特点 ,同时对进口成洞、渐变段开挖和锚固的处理措施及参数 ,很具有代表性。特别是对地质构造和岩体稳定分析处理都有独特的特点 ;既保证边坡稳定和成洞安全 ,又保证了工期。岩体构造、地质构造分析和锚固参数对相类似的工程都有很高参考价值和借鉴意义
The geological condition under the elevation of 1981m on the inlet slope of the discharge tunnel at the left bank of Gongboxia hydropower Station is complex with interlaced faultages. The treatment of the tunnels face slope and the anchor of collapse on the left slope have own peculiarities, at the same time the formation of tunnel inlet and the excavation and anchor of transition section are typical. Especially the analysis of geological structure and its stability have particular features, which ensure not only the slope stability and the safety of tunnel formation, but also the construction schedule. The analysis of rock structure and geological structure provide reference for similar projects.
