摘要
土钉支护内部整体稳定性分析常用Bishop条分法和Fellenius条分法。已有的计算方法大多数是将土钉对土体的抗滑作用与土体本身的抗滑作用分开考虑,将两者合并考虑进行稳定性分析,得出了相应的计算公式,在圆弧滑动面的假设下,基于混沌优化利用该方法对某一工程实例进行了分析,得出了每一开挖步骤的安全系数和危险滑动面。
Two major methods, including Bishop method and Fellenius method, are frequently used in internal overall stability analysis of soil nailing.Anti-sliding effects of soil nails and soil itself, are commonly calculated separately.Synthesis of two effects is studied, and an improved Bishop method is put forward.Based on assumption of circle surfaces, a case of soil nailing is researched through chaotic optimization, safety factors and dangerous sliding surfaces of each of construction step are obtained.
