摘要(Abstract):
本文结合漫湾电站的爆破施工对高边坡的安全稳定问题进行现场试验与理论分析,提出了边坡开挖爆破动力稳定分析计算方法,解决了设计与施工中的关键技术问题。
Combined with the blasting construction of Manwan Hydropower Station,the site experiment and theoretical analysis on the safety and stability of high rock slope has been done in this paper.One calculation method of dynamic stability analysis proposed on the basis of the theory of limit equilibrium of rigid body.The major technical problems have been solved in engineering design and construction.In addition,the practice for solving the slope excavation of left bank and stability analysis at Manwan Hydropower Station is also introduced in this paper.
