現阶段人们正通过各种方法对铁路隧道衬砌計算理論进行大力的研究。几年来我們在实际計算工作中也曾遇到过不少問題,本文仅就有关影响直墙式衬砌計算强度和精度的問題,谈談自己的实际体会,希望得到大家的指正和补充。一、与衬砌强度有关的几个因素一般講来,衬砌結構在强度上最薄弱的即对强度起控制作用的位置是顶截面。經驗表明,直墙式衬砌强度的影响問題,应分拱部和边墙而言,因为有关拱部和边墙的备物理力学因素,对衬砌强度影响的比重是不一样的,一般說来拱部影响大些,边墙小些
At this stage, people are going through a variety of methods to study the calculation theory of railway tunnel lining vigorously. Over the past few years we have encountered many problems in the actual calculation work. This article only on the calculation of the strength and accuracy of straight wall lining problems, talk about my own experience, I hope everyone correct and complement. First, several factors related to the lining strength In general, the lining structure in the strength of the weakest point that is the role of control of the intensity of the top cross-section. Experience shows that the impact of the strength of straight wall lining should be divided arch and edge of the wall, because the arch and the edge of the wall for the preparation of physical and mechanical factors, the impact on the lining strength is not the same proportion, in general, arches Ministry of influence larger, smaller side walls
