摘要：Triaxial compression tests had been performed to determine the properties of the rock mass around unlining underground crude oil a storage cavern which was the first one in China. The execution situation of the tunnel project and the seepage law of groundwater were taken into account. The stress and the seepage field around the tunnel in different working states were simulated by applying Comsol around a underground crude oil storage caverns. According to the test results, it was found that the excavation process may arise the local damage. The extension of the loose zone induced by excavation ranged from 0 to 15.6 m, depending on the buried depth of the caverns. According to numerical simulation results, the crown settlement and stress concentration was depended on the buried depth and the water pressure distribution after excavation of the main cavity.This research results can provide the reference for analysis on the stability of the underground cavities under low stress level and on the water sealed underground petroleum storage rock caverns.
