摘要
抗滑桩临界桩距的基兹布尔格算法考虑了土拱作用,是当前国内外几种临界桩距算法中理论上最为合理的算法之一.分析了基兹布尔格临界桩距计算公式中的3点不足,通过对其进行修正,重新推导出抗滑桩临界间距的计算公式,改进后的算法克服了原有不足,较全面反映了临界桩距与桩宽、滑体性质以及滑坡推力之间的关系.算例对比表明,改进后的算法更切合实际.
When Kisberge method for calculation of critical spacing of slide-resistant piles is applied to soil arching effect, it becomes one of the most reasonable methods among various existing critical spacing calculation methods at home and abroad. Yet there are some disadvantages in the Kisberge method. Corresponding improvement is made to reduce the calculation formulas. The improved formulas comprehensively reflect the relationship between critical spacing and pile＇s width, landslide characteristics and slide thrust, Calculation example indicates that the improved method is practical in construction engineering .
