摘要
针对隧道仰拱底鼓产生的危害,文章从自然环境、人为因素、灾害等方面简要分析了其产生机理,在此基础上提出了三个假设条件对薄板压曲微分方程进行简化,归纳出影响隧道仰拱底鼓的七个关键点,并对各关键点检测方法的适用性进行分析;总结了针对各关键点所采取的防治措施。基于某隧道工程仰拱底鼓检测实例,初步验证了本文研究结果的正确性。
The mechanism of tunnel invert heaving is analyzed from the three aspects of natural environment,human 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.
