摘　　要：金桥水电站地下厂房设计最大开挖尺寸为83.8 m×20 m×35.4 m(长×宽×高),是目前西藏自治区水电工程首个地下厂房,为确保施工进度,采用立体多层平行开挖的方案,实现了"竖向多层次,平面多工序"的立体开挖,确保了地下厂房开挖施工工期。The maximum excavation size of the underground powerhouse of Jinqiao Hydropower Station is designed as 83. 8 m ×20 m × 35. 4 m（ length × width × height）. It is the first underground powerhouse of hydropower project in Tibet. To ensure the construction progress,a three-dimensional multi-layer parallel excavation scheme is adopted. The excavation scheme achieves a three-dimensional excavation of ＂ multi-layer in vertical surface and multi-process in horizontal surface ＂, and thus the excavation construction period of underground powerhouse is ensured.
