选取岩石抗压强度、完整系数、结构面状态、地下水发育情况、洞轴线与软弱结构面的夹角作为地下储油库工程围岩稳定性的评价因素,并采用权重反分析的方法确定各指标的权重,建立了基于权重反分析方法和功效系数法的洞库围岩稳定性评价模型。最后,将建立的围岩分类模型应用于实际工程,通过与实际开挖结果对比表明,模型判别结果与实际开挖揭露围岩类别相吻合,证明了该方法用于地下储油洞库围岩分类的合理性和有效性,为地下储油洞库围岩稳定性判别提供了一种新思路。
選取巖石抗壓彊度、完整繫數、結構麵狀態、地下水髮育情況、洞軸線與軟弱結構麵的夾角作為地下儲油庫工程圍巖穩定性的評價因素,併採用權重反分析的方法確定各指標的權重,建立瞭基于權重反分析方法和功效繫數法的洞庫圍巖穩定性評價模型。最後,將建立的圍巖分類模型應用于實際工程,通過與實際開挖結果對比錶明,模型判彆結果與實際開挖揭露圍巖類彆相吻閤,證明瞭該方法用于地下儲油洞庫圍巖分類的閤理性和有效性,為地下儲油洞庫圍巖穩定性判彆提供瞭一種新思路。

Based on weights back analysis and efficiency coefficient method, a new surrounding rock classification model of underground oil storage caverns is put forward. And rock compressive strength, integrated coefficient, character of discontinuity, groundwater, the angle between tunnel axis and soft surface are selected as key factors of surrounding rock stability. Then using weights back analysis method to determine the weights of factors, after which the model of the surrounding rock classification can be established based on weights back analysis method and efficacy coefficient method. Finally, the established classification of surrounding rocks model is used in practice;and the results show that the outcomes of stability analysis match the actual surrounding rock classification. It proves that the method used in surrounding rock classification of underground oil storage caverns is rational and effective, so as to provide a new idea to predict surrounding rock criterion for underground oil storage caverns stability.
