| 摘 要： | 土钉支护模型多被简化为平面应变问题,土钉间沿竖向土拱效应成了主要的考虑因素。若考虑问题的空间性,则可建立基于水平土拱效应的钉土相互作用理论。在土钉墙内部应力分析中,将竖向平均应力作为重要的一个方面,可通过给定有限的假设得到解析解。基于水平土拱原理推导了竖向平均应力和水平平均应力的计算式,并通过实例进行了讨论。

| Abstract: | Soil nailing model is commonly simplified into plane strain issues.Vertical soil arching effect becomes the main considering factor.If considering space,soil-nail interaction theory can be established based on horizontal soil arching effect.In analysis of soil nailed wall internal stress,the solution of average vertical stress,as an important factor,can be solved by giving finite assumption.In this paper,the calculation formula of average vertical stress and average horizontal stress are educed based on hor... |
