范文田老师在这篇文章里对确定直墙式地下结构拱部弹性抗力上零点位置的計算方法,提出了简化意見。由于上零点位置确定得正确与否对衬砌內計算的結果影响較大,所以这些意見在刊登以前就引起了設計部門一些同志的兴趣和爭論。据了解某些論点至今仍存在分歧。我們現在刊載这篇文章的目的,只是企图引起更多讀者的爭鳴。希望大家能把自已的不同看法写給本刊,使討論深入,以利于問题的进一步解决。
In this article, Ms. Fan Wentian proposed simplified methods for determining the zero point position of the elastic resistance of the vertical wall type underground structure arch. Because the correct determination of the upper zero point has a great influence on the results calculated in the lining, these opinions have caused interest and controversy among some comrades in the design department before it was published. It is understood that there are still differences between certain arguments. The purpose of the article we are publishing now is to try to arouse the enthusiasm of more readers. I hope that everyone can write their own different views to this journal to deepen the discussion so as to facilitate the further resolution of the issue.
