摘要
江苏溧阳抽水蓄能电站地下厂房所处围岩较差,工程地质条件错综复杂,厂区断层发育密度大,施工安全问题极为突出。溧阳地下厂房采用顶拱开挖与支护的施工方法。通过实践证明该施工方法能保证在复杂地质条件下,大跨度地下厂房顶拱开挖与支护的施工安全、质量和进度。
The surrounding rock and the engineering geological conditions where the underground powerhouse of Liyang Pumped Storage Power Plant is located are poor and complicated. The faults in the plant area are developed largely in term of intensity. Its construction safety is serious accordingly. The underground powerhouse crown of the power plant is supported while excavated. The engineering practice proves that this construction method can assure the safety, quality and progress of the excavation and support of the large-span underground powerhouse crown under the complicated geological conditions.
