Study On The Influence Of Diabase Dikes’ Development To Underground Water Sealed Oil Storage Cavern’s Stability

The stability of underground water sealed oil storage cavern is the key to the safe construction and normal operation of oil storage. During the construction, if cavern excavation is in the surrounding rock which is transformed by the injected dikes, there will be adverse effects on the stability of cavern. With this situation, a lot of accidents occurred during the construction like collapse and water inrush. As a matter of fact, it is necessary to do the research on the influence of injected Dikes’ to cavern’s stability. And this paper mainly works on the influence of Diabase Dikes’ development to underground water sealed oil storage cavern’s stabilityThis paper studied the influence of Diabase Dikes’ development to underground water sealed oil storage cavern’s stability based on a 5 million cubic meter underground water sealed oil storage construction project combining the project survey report and field practice.This paper’s achievements mainly include these below:(1) Diabasic dike and the granite’s structure surface cutting across forming the key block which is a adverse effect on the stability of cavern.(2) Diabasic dike’s injection is the key effect of the transformation of granite. During this process, fractured rock is formed which is the key to cavern’s stability.(3) Calculated the cavern’s stability by using ABAQUS, analyzed the regulation of the influence of Diabase Dikes to cavern’s stability.
