| 摘 要： | 基于土拱效应理论,针对边坡稳定分析中抗滑桩的合理间距进行分析。文中对比分析了以往文献中的不同方法,通过分析相邻拱脚截面静力平衡关系、拱顶截面前缘点最大主应力公式、拱脚截面强度条件的3个方程,推导出了桩间净距的计算公式,并结合工程实例进行了验证。

| Abstract: | Based on the soil arch effect, the reasonable spacing of the piles against sliding in the slope stability is analyzed. In the pa- per, different methods recorded previously are compared and analyzed. The formula for computation of the net spacing between piles is derived through three equations for the static balance relationship of the neighboring arch foot section, the maximum principal stress at the front edge point of the arch top section and the arch foot section strength. The derived formula is verified through the engineering practice as well. |
