| 英文摘要 | The stability of underground engineering is an important part of risk analysis. This study has developed a new method of oil storage caverns stability analysis by combination of uniform design, regression analysis, variable selection and numerical experiments. Firstly, considering there are many stability influencing factors, such as the elastic modulus, Poisson ratio, friction angle, cohesion, tensile strength, cavern depth, lateral pressure coefficient, permeability coefficient, and span ratio, it is reasonable to lay down numerical experiment scheme by uniform design. After that, numerical analysis of caverns stability is carried out with the finite difference method and point safety factor as the target value. Through the use of quadratic regression model and stepwise regression variable selection method, mathematical statistics model of point safety factor is established according to numerical results. The model is verified by the comparison between model predicted value and numerical experimental result. Then, isopleth maps of point safety factor are drawn based on established mathematical statistical model, meantime, to analyze regularity of the effect of above factors on caverns stability. |
