摘　　要：西藏金桥水电站调压井原设计方案为气垫式,综合考虑后调整优化为阻抗式。在调压井施工过程中,受到多种因素影响导致工期滞后,为保证发电目标工期,对开挖施工方案和衬砌结构进行了调整优化。通过设计方案和施工方案的调整优化,金桥水电站调压井从结构布置上更为科学合理,工程建设目标工期也顺利实现。The original surge shaft of Jinqiao Hydropower Station in Tibet is designed as an air-cushion type. After comprehensive consideration,the surge shaft is adjusted as an impedance type. In the process of construction of surge shaft,the construction duration lags behind as influenced by a variety of factors. In order to ensure the target duration of power generation,the excavation scheme and lining structure are optimized. Through the optimization of design scheme and construction plans,the surge shaft of station is more scientific and rational from the structural arrangement,and the construction target duration is also successfully guaranteed.
