摘要
采用FLAC3D有限差分程序对某水电站大型长廊阻抗式调压井的洞室开挖围岩稳定、衬砌结构受力特性进行分析计算。分析了围岩和支护结构联合作用的机理,并提出相应的分析方法。结果表明:在现有的支护措施下围岩的稳定是有保证的,也说明采用有限差分法对围岩和支护结构联合作用进行分析是有效、可行的。
The chamber surrounding rock stability and mechanics of lining structure of large and long throttled surge tank is analyzed and computed by FLAC30 software.The co-action mechanism of surrounding rock and support structure is analyzed and correspondent analysis method is put forward.The analysis and computation results show the surrounding rock stability can be guaranteed by existing support measure and the analysis on the co-action of surrounding rock and support structure by Finite Difference Method is effective and feasible.
