By properly selecting the main physical and mechanical parameters of surrounding rock
a model for calculating water inflow of a large underground water seal oil cavern after the whole section excavation is established based on porous elastic continuum fluid-solid coupling theory. And the groundwater seepage field and displacement field of Huangdao oil storage underground water seal cavern are analyzed with numerical simulation. By the comparative analysis of different grouting mode and different thickness of grouting case
it is found that it is not a fact that the greater the thickness of grouting circle of cavern
the better control effect of the seepage flow. There is a relatively economic and reasonable threshold. The results show that the best way of post-grouting is to form a whole section closing grouting circle
