承压水上井筒底板隔水层加固厚度的突变分析

Catastrophic Analysis on the Thickness of Consolidation for the Water Retarding Formation at the Bottom of Shaft Above the Loaded Water Body

在薄隔水层井筒底板突水突变模型的基础上,建立了承压水上井筒底板隔水层加固厚度的突变模型,利用该模型可确定井筒底板隔水层的最小加固厚度。该模型在实际工程中的应用表明,其计算结果符合实际工程的要求,可确保安全上可靠、经济上合理。本文的研究思路和结论对类似条件下圆形薄板状工程结构的突变分析具有重要的参考价值。

On the basis of the catastrophic model of water outburst at the bottom of shaft in the thin water retarding formation, a catastrophic model is established for the thickness of the consolidation of the water retarding formation at the bottom of shaft above the loaded water body. The minimum thickness of consolidation in a practical shaft bottem can be calculated using this model. It is demonstrated in practical application that the calculation results obtained using this model can satisfy the requirements for practical engineering projects and can guarantee reliability in safety and feasibility in economy. The research ideas and the conclusions presented in this paper provide significant reference value to the catastrophic analysis of circular thin plate engineering structures under similar conditions.
