This study analyses the developments in researches on the disasters during cavern construction in salt beds with multi-interlayer. Relative to the foreign large salt dome landscape, there are many layers of mudstone in salt beds which has a thin single layer. And such special geological conditions increase the difficulty of solution mining in the control of cavity shape and stability of the cavity, which easily leads to disasters. To statistical analysis the disasters in process of cavern building with multi-interlayer in china, it show that: taking Chinese geological conditions for example, the disasters during cavern construction in salt beds with multi-interlayer caused the failure of cavity can be divided into three categories: geological conditions in beds; the damage of cavity wall in the process of cavity building; the distortion of cavity shape expansion. To analyze predisposing factors lead to salt cavern storage failure in detail, the mechanism of the corresponding factors lead to disaster has been summarized. Finally , some suggestions has been proposed to avoid the disaster maybe happened.
Key words: Multi-interlayer, the shape deformity, the interlayer collapse, the surface subsidence, washing techniques, ,
