| 摘 要： | 鉴于现行规范关于斜坡路基基底台阶宽度的经验性规定,对潜在滑移面力学参数与台阶宽度的关系进行理论研究。介绍滞水层的形成机理,分析滞水层与填土体的共同作用,从力学角度建立了数学模型,推导出基底台阶合理宽度的计算式。建议修改相关规范条文,按推荐计算式确定台阶宽度,且要求台阶宽度不小于2 m,以更有效地提高边坡稳定性。

| Abstract: | According to the current specification on empirical regulations of slope roadbed bench width,the relationship between mechanical parameters of potential sliding face and bench width is studied theoretically in this paper.Besides,mathematical model is established from the point of mechanics through introducing the formation mechanism of aquifer and analyzing the interaction between aquifer and filling soil,and thus the formula of roadbed bench reasonable width is educed.It is recommended to modify the releva... |
