作为一种常用的支护方式，抗滑桩在露天矿滑坡治理中发挥着巨大的作用。抗滑桩设计的重要指标之一就是桩间距，在以往的研究成果中并没有完整的确定桩间距的理论和方法。通过对抗滑桩桩间土拱效应的研究，从桩侧与边坡土体间的摩擦阻力及黏着力承担滑坡推力的静力平衡条件和土拱拱脚处与跨中截面的强度条件2个方面进行分析，建立了桩间距的计算公式。工程实践表明，所建立的抗滑桩间距计算公式的计算结果较为合理，对于露天开采边坡加固工程具有一定的实用价值。

The anti-slide pile plays an indispensible role in landslide treatment as a common supporting way .An important indicator in anti-slide pile designing is the pile spacing .However,there are no integral theories and methods to determine the piles spacing in previous studies .The paper studied the soil arch effect between piles , analyzed the balancing conditions among the many forces produced between piles and stope ,and the strength conditions at the foot of soil arch and across the section ,and finally established the calculation formula of the pile spacing .The engineering practice shows that the calculation of anti-slide pile spacing formula is more reasonable and the method is of value to similar engineering applications .
