摘要
结合古城水电站厂房基础开挖,对深基坑支护技术进行了探讨,介绍了支护方案及其投资,进行了方案比选,并重点对地下连续墙方案进行了边坡稳定计算,结果满足规范的要求,表明地下连续墙方案在投资及施工方面具有一定的可行性;深基坑方案可有效地减少开挖量,但风险较大。
The application of supporting techniques for deep foundation pit in powerhouse excavation of Gucheng Hydro- power Station is discussed. Supporting schemes and their investment are introduced and compared. The side slope stability of underground continuous walls is calculated and its results meet the requirements of specification, which indicate that underground continuous walls are feasible in terms of investment and construction and that the deep foundation pit scheme has the features of decreased excavation quantity but with higher risk.
