摘　　要：柳坪电站调压井为整个电站四个土建标的关键线路之一,其结构复杂,岩石条件差,上调压井道路地形陡峭,施工安全风险突出,工期尤其紧张。在施工过程中大胆进行技术革新,优化上调压井施工道路、增设施工支洞、采用模喷混凝土代替顶拱衬砌混凝土施工、根据调压井的结构和需要采用电动葫芦及开挖等先进的施工技术,在工期和安全上取得良好效果,对以后类似工程也有借鉴之处。Liu Ping surge shaft is the key in the four subjects of the entire power plant construction.Due to its complex structure of the rock conditions,killing up steep terrain road and high risk of construction,the time allocated for a project is very limit.During the construction process,lots of technologies have been improved,such as killing up to optimize the construction of roads,construction of an additional branch hole model used in place of concrete sprayed concrete lining the top arch construction,according to the surge tank＇s structure and application of electric hoist,and other advanced excavation and construction technology.The security improved a lot and the construction period was reduced also.This project has a good reference for the similar projects.
