地下水封洞库施工巷道密封塞设计探讨

Study on the Necessary of Water Curtain for the Underground Water Seal Oil Storeroom

建设地下水封洞库是现阶段大型石油储备基地的重要发展方向,其中施工巷道密封塞是地下水封洞库结构体系中重要的结构组成部分,也是受力最大、设计最复杂的构件。文章结合国内外地下水封石油洞库的工程设计经验,根据在建某洞库的工程地质条件,运用MIDASGTSNX软件对施工巷道密封塞的部分设计参数进行建模计算和分析对比,并结合其他相关工程因素,提出合理的优化设计意见,为今后的施工巷道密封塞设计提供必要的依据。

Construction of underground water-sealed cavern is an important development direction of large-scale petroleum reserve base at present.The construction roadway sealing plug is an important structural component in the structure system of underground water-sealed cavern,and it is also one of the components with the largest force and the most complex design.Based on the engineering design experience of underground water-sealed petroleum Caverns at home and abroad,according to the engineering geological conditions of a cavern under construction,this paper uses MIDAS GTSNX software to model,calculate and analyze some design parameters of sealing plugs in construction roadways,and combines with other relevant engineering factors,puts forward reasonable optimum design opinions for the future.The design of sealing plug in construction roadway provides necessary basis.
