| 摘 要： | 基坑支护结构的嵌固深度既是基坑坑底抗隆起稳定性的需要,也是保证支护结构具有足够的抗倾覆稳定性的需要,基于规范设计方法,分析了弹性法、圆弧滑动法、考虑横撑力的圆弧滑动法和规范经验法等方法确定嵌固深度的差异;从考虑地基土性能的离散性出发,给出了嵌固深度的取值范围.

| Abstract: | The embedded depth of retaining structure of pit satisfies not only the anti-heaving stability of pit bottom but also anti-overturning stability of retaining structure.Based on codes,the calculating difference of embedded depth was analyzed with the some methods including elastic method,arc-slippage method,arc-slippage method considered the horizontal brace force and empirical law of the code.Then the acceptable range of embedded depth was proposed considered the discreteness of soil mechanical property. |
