Abstract The mechanism of tunnel invert heaving is analyzed from the three aspects of natural environment, hu? man factors and disaster, aiming at the hazards caused by tunnel invert heaving. Three hypotheses for simplification of differential equation of thin plate buckling are proposed, the seven key points affecting tunnel invert heaving are summarized, the applicability of the inspection method for the seven key points is analyzed, and the corresponding preventive measures are summarized. Based on the invert heaving inspection of certain tunnel, the correctness of this study is verified to some extent.
