基于粗糙集的载体桩质量核心影响因素分析

针对载体桩质量不容易控制的特点,在剖析载体桩承载机理的基础上,分析了影响载体桩质量的各因素,并引入粗糙集理论,建立了影响因素约简模型。以邯郸地区载体桩工程为例,通过模型约简得出最小的影响因素集,从而确立了影响载体桩质量的核心影响因素,为载体桩的质量预测和控制提供理论依据。结果显示该方法克服了目前人们以主观和定性分析为主的缺点,可信度较高。

Study on the core factors affecting the quality of pile with bearing base based on rough set

Based on the characteristics of quality of pile with bearing base difficult to control,the influencing factors of pile quality are analyzed,and the reduction model of influencing factors is established according to the rough set theory.With the example of the pile project with bearing base in Handan city,the minimal influencing factors set are obtained,and the core influencing factors of pile with bearing base quality are built,which provides theoretical basis for quality prediction and the control of pile with bearing base.The results show that the method overcomes the subjective and qualitative factors and achieves with high reliability.
