| 摘 要： | 根据乌鞘岭隧道岭脊地段地质状况和二次衬砌实际受力特点,采用拟地基曲梁计算法来分析二次衬砌的裂缝宽度与间距.通过对乌鞘岭隧道岭脊段三种不同地质状况下二次衬砌裂缝宽度与间距的计算分析,发现二次衬砌受力越大,越接近实际出现的裂缝状况.对于该处的衬砌裂缝有一定的预测作用,对二次衬砌同类受力情况下的裂缝宽度与间距计算,也有一定的参考价值.

| Abstract: | This paper discussed the calculation analysis of the secondary lining crack width and spacing by using simulating soil curved beam's stress.Through calculation analysis of concrete crack width and spacing of the lining under three different gcological conditions of the ridge,it was found that when the lining was under larger load the calculation result was more close to the actual crack state.The result is helpful for the calculation analysis of crack width and spacing of secondary lining under similar loading. |
