摘要: 目前国内正在大规模兴建盐岩地下储库群,其规划设计阶段可优化因素较多,且各因素影响程度不同,选取椭球形腔体几何分布形式、矿柱宽度和夹层位置3个主要因素进行了综合优化研究,旨在分析3个因素的敏感性影响程度,并确立储库群最优形式。对3个因素分别设立3个水平,运用正交试验设计原理,确立了9组试验方案,进行了相关数值模拟试验。评价层状盐岩地下储库群时选用经改进的位移、应力试验指标,基于试验结果运用正交试验法中的极差分析和方差分析对3个因素进行详细分析。结果表明,3个因素中夹层位置影响最显著,矿柱宽度居次,椭球形腔体几何分布形式影响最弱;最优储库群形式为邻腔夹角60°的分布形式、2.0D矿柱宽度、夹层分布在腔体上部1/4H(H为腔体高度)位置。

Abstract: At present, there is a large-scale construction of salt rock storage groups in China. Many optimizable factors exist in the planning and design phase with different influencing magnitudes. The three main factors, i.e. the geometric distribution of ellipsoidal caves, the width of pillars and the position of the interlayer, are selected to be studied. The purpose of the research is to analyze the influence degree of the three factors and to determine the optimal storage group form. Three levels are set for each factor and nine text schemes are made based on the principle of orthogonal experimental design; and the related numerical simulation experiments are conducted. The improved experimental index of displacement and stress is chosen to evaluate laminated salt rock storage group. Using extreme difference analysis and variance analysis, the test results are analyzed in detail. The research results show: among the three factors, the position of the interlayer has the most significant influence, the width of pillars is in the second place and the geometric distribution of ellipsoidal caves is the third. The optimal storage group form: the angle of the adjacent caves is 60°, the width of pillars is 2.0D and the interlayer is distributed in upper 1/4H of the cavity.

Key words: the laminated salt rock storage group, multi-factor optimization, orthogonal experimental design, extreme difference analysis, variance analysis
