摘要
在总结了大量工程实例的基础上,对深切河谷高边坡的坡体结构进行了详细的研究,并对坡体结构进行了科学的分类。对锦屏一级水电站高边坡稳定性分析采用改进的极限分析Sarm a法与三维多重网格极限平衡法,并通过工程实例验证了方法的可行性与适用性,为深切河谷高地应力区边坡稳定分析提供了更为合理的分析方法。在对锦屏一级水电站边坡稳定综合分析的基础上,提出了科学合理的高边坡支护设计方案,并对支护后的高边坡进行了稳定性计算,验证了所设计的高边坡支护方案是合理可靠的。
On the basis of summarization of large amount of construction practices,the slope structure of deep incised river valley slope is researched in detail and classified scientifically.The improved Sarma method and 3-D multi-network limit equilibrium analysis method are put forward for side-slope of Jinping I Hydropower Station,and the feasibility and practicality of the methods are verified by practical case,which provides more reasonable analysis method for side-slope stability analysis in high ground stress area.Based on comprehensive analysis of side-slope stability of Jinping I Hydropower Station,scientific and reasonable support scheme for high side-slope is put forward and the stability analysis for supported high side-slope is conducted.The analysis proves the design scheme for high side-slope is reasonable and reliable.
