| 摘 要： | 盐岩矿床中难溶泥质夹层的存在给地下储库水溶造腔带来了诸多不利影响，如何有效地预测与控制水溶造腔过程中泥质夹层的垮塌成为亟待解决的技术难题。夹层垮塌力学机制研究以该问题为背景，建立了水溶造腔过程中夹层垮塌分析的力学模型，并应用弹性板壳理论进行了求解，根据求解结果对夹层因局部破损及整体失稳引起垮塌的力学机制分别进行了论述，对夹层垮塌的力学机理进行了总结，给出了一种计算夹层极限跨度的方法。研究成果对水溶造腔过程中夹层垮塌的预测与控制有重要指导意义。 |

| Abstract: | The existence of indissolvable interlayers leads to many adverse effects for building salt cavern storages by solution mining. It is an urgent technical problem that how to forecast and control the collapse of indissolvable interlayers. The problem is the research background of mechanism of interlayer collapse. A mechanical model for interlayer collapse study is established and solved by theory of plate and shell. Based on the solution, the mechanisms of collapse caused by partial failure and integral instability are analyzed. And then all the mechanisms of collapse are summarized. Finally, a method for calculating limit diameter of interlayer is proposed. The conclusions of the research have significant meaning for forecasting and controlling interlayer collapse in solution mining. |
