摘要： 针对某地下水封储油洞库群的实际工程情况，基于正交试验设计方法，选取锚杆长度、锚杆间排距、喷射混凝土厚度和钢拱架间距4个因素，各个因素分别设立3个水平，确立9组试验方案，采用FLAC3D数值模拟软件进行相关模拟试验，最后以关键点位移及塑性区体积为评价指标对试验结果进行分析以优化洞库群支护方案.结果表明，钢拱架间距影响最显著，锚杆间排距及长度影响最弱；优化后的支护方案为锚杆长度5m、锚杆间排距2m×2m、喷射混凝土厚度120mm、钢拱架间距1.5m.该研究成果能够有效保证该工程区围岩的稳定.

Abstract: According to the actual engineering of oil storage caverns， the orthogonal experiments were conducted. Four factors were selected， including the bolt length， the bolt spacing， the thickness of shotcrete and steel arch spacing， and three levels were set for each factor so that nine test schemes were performed. Then the corresponding numerical simulation by using FLAC3D was conducted in order to optimize the supporting scheme. The key point displacement and plastic zone volume were taken as the evaluating index. Results showed that the steel arch spacing was the key parameter for supporting other than the bolt length and bolt spacing. An optimized supporting scheme of 5m bolt length with bolt spacing of 2m × 2m， a shotcrete thickness of 120mm and a steel arch spacing of 1.5m were adopted， which could control the stability of the surrounding rock of these caverns effectively and give some references to similar projects.

Key words: underground oil storage caverns, supporting optimization, orthogonal design, FLAC3D, stability of surrounding rock
