摘要
三峡右岸大坝1A标右厂坝段基岩倾向下游的长大中、缓倾角裂隙相对较发育,厂房机窝开挖致使坝后存在高陡临空面;右非坝基圆弧段开挖后较发育的中、缓倾角结构面与边坡临空面组合,均对坝基抗滑稳定和边坡稳定不利。为改善上述部位地质条件,设计先后共布置284束锚索,通过施工单位历时16个月的精心施工和监理单位严格控制,施工质量良好,满足设计要求。主要介绍锚索工程施工监理质量控制情况。
In the foundation rock of the right powerhouse dam section of the Three Gorges dam,there were long,large,relatively developed and downstream-tilted fissures of medium and low angle.The excavation of turbine pits brought about high and steep exposed surfaces.After the excavation of the dam foundation of the circular arc section at right non-overflow dam,the combination of the developed structural lanes of medium and low angle with the exposed faces of side slopes was unfavorable to the stability of dam foundation and side slopes.In order to improve the geologic conditions of the above-mentioned localities,284 anchorage cables were arranged.The construction quality of these anchorage cables was very good and met design requirements due to 16 months of elaborate construction by the construction unit and strict quality control by supervisory unit.This paper mainly presents the quality control in the construction supervision of the anchorage cable engineering.
