摘要:
大甲溪发电厂青山分厂复建工程位于台湾中部山区大甲溪中上游,新建地下工程主要有:地下开关场、尾水隧道延长段及厂区对外联络信道,这些地下工程遭遇的岩层主要由向东倾斜的变质砂岩及板岩组成,其间存在甚多褶皱构造与剪裂构造,造成施工过程遭遇甚多地质灾害与困难,包括:开挖能量低、隧道沉陷、落盘及抽坍等,经工程团队戮力合作,终能克服不利地质环境,顺利完成新建地下工程。
关键词: 地下开关场, 褶皱构造, 抽坍
Abstract:
The project located at the upstream of Tachia River, mountainous area of central Taiwan. The newly-built underground construction includes underground switch yard, elongated section of tailrace tunnel and access roads. The geology of the underground construction site consists of eastward dipping metamorphic sandstone and slate with numerous folds and shearing structures which leaded to substantial difficulty. It includes slow excavation, tunnel subsidence, and collapse. Still after remarkable efforts of teamwork, all the disadvantages were conquered eventually.
Key words: underground switch yard, fold, collapse
