摘要
为了降低主观和客观因素对桩基成孔方案的影响,确定最优施工方案,通过模糊综合评价指标构建,借助SPSSPRO工具和等腰三角形分段函数,对桥梁桩基成孔方案进行分析。以某大桥5种施工方法为例进行了验证,结果显示:旋挖挖孔>人工挖孔>机械冲孔>爆破成孔>机械钻孔,该项目证实了旋挖成孔施工速率最快、更为环保,安全性较高,综合成本较低,通过该方法有效提高了施工方案选择的客观性和合理性。
In order to reduce the influence of subjective and objective factors on the pile foundation drilling scheme and determine the optimal construction scheme,this paper constructs the pile foundation drilling scheme by using the Fuzzy Comprehensive Evaluation Index,SPSSPRO tool and the isosceles triangle subsection function,the pore-forming scheme of Bridge Pile Foundation is analyzed.Five construction methods of a certain bridge were used as examples for verification.The results showed:rotary drilling>manual drilling>mechanical punching>blasting holes>mechanical drilling.This project confirmed Rotary drilling has the fastest construction speed,is more environmentally friendly,has higher safety and lower overall cost.This method effectively improves the objectivity and rationality of construction plan selection.
