天荒坪电站500 kV开关站开挖与边坡整治施工——兼论开挖爆破对高边坡稳定的影响及对策

Excavation and Slope Treatment for 500kV Substation of Tianhuangping Pumped -Storage Hydroplant

在大型水利水电施工中，经常遇到岩质高边坡稳定问题，天荒坪抽水蓄能电站５００ｋＶ开关站所处的地形地质条件非常复杂，本文着重介绍在边坡开挖和支护过程中，根据不同的地形地质情况所采取的控制爆破和支护措施。

It is very often to encounter the high rock slope stability problem in construction of a water conservancy project or a hydropower project. The 500 kV substation of the Tianhuangping pumped-storage hydropower station is located in a topographically and geologically complicated area. This paper deals with the controlled blasting and supporting measures taken in the light of the different topographical and geological conditions during the slope excavation and supporting.
