摘要 结合三峡水利枢纽右岸三期电站厂房基础开挖施工过程中,厂房基础上游高边坡面存在较发育的裂隙和缓斜角结构面的实际情况,对于深层不良地质块体采用预应力锚索进行加固处理。对预应力锚索施工各道工序按规范与设计技术要求严格控制,通过各项检测和观察,处理效果显著。 During the third - stage excavation of powerhouse foundation for left - bank plant of Three Gorges Project, there occur developed fissures and structural plane with gentle bevel on upstream slope of powerhouse foundation, thus deep unfavorable geologic massif was reinforced with prestressed anchorage cables. Each operational sequence of prestressed anchorage cable was rigidly controlled as per the Code and the Design Specifications. By check and observation of each item, the treatment effect was significant.
