| 摘 要： | 采用固支大变形圆板突变模型研究了单井溶腔顶板的稳定性，得出了溶腔顶板岩层失稳的必要条件；并考虑了自重侧压力及水平构造应力的综合作用，用平直梁尖点突变模型研究了连通井顶板的失稳突跳，得出了连通井顶板失稳的充要条件。为溶腔稳定性控制和溶腔用于战略石油和天然气的储备打下理论基础。

| Abstract: | The stability of single cavern roof is studied with cusp catastrophe model of large deformation circular plate with fixed supports. The necessary conditions of instability are deduced. Considering the level stress contributed under the weight of strata and geological construction, the cusp catastrophe of connected well roof is analyzed with cusp catastrophe model of beam model. The sufficient and necessary condition of instability is deduced, which is the theoretical base of the cavern’s stability controlling and national strategic oil storage in the cavern. |
