摘　　要：大跨度、复杂地质条件下调压井穹顶的成型要求较高,施工难度较大。通过应用UDEC离散元软件,模拟在节理裂隙发育条件下穹顶开挖稳定性并提出支护建议,为穹顶设计及施工提供依据。For the long-span dome shaped tank requires high construction difficulty. The UDEC discrete element software is used to simulate the stability and support of the dome under the condition of joint fracture development, which provides a basis for the design and construction of the dome.
