| 摘 要： | 从方桩桩间土拱形成的机理、力学特性入手,将广泛应用于隧道工程的普氏系数引入抗滑桩最大间距的计算分析中,并根据桩间土拱的静力平衡,建立了相应的计算模型。同时以泸州市世寿街滑坡为例,对所推导的最大桩间距计算公式进行验证,计算结果为1 75m,与实际工程设计基本一致。

| Abstract: | This paper starts from the principle and the mechanic characteristic of forming soil arch between square piles, and applies the M.M. PROMOJIYFAKONOV parameter which is widely used in tunnel engineering to the analysis of maximum space between anti-slide piles. In accordance with static equilibrium of the soil arch between two anti-slide piles, the computation model to define the maximum space between two anti-slide piles has been set up. Shishoujie landslide is cited to verify the formulae. The computation result is 1.75 m, and the space between the anti-slide piles executed in situ is 1.8 m. The computation consists with evidence in the field. |
