摘要
从系统工程方法论的角度出发,以物理-事理-人理(WSR)方法论为指导,从粗粒土的物理属性、外界因素、试验操作等3个方面全方位多角度地分析总结了压实试验中影响干密度的因素,建立了基于WSR方法的振动压实试验中粗粒土干密度影响因素指标体系,并运用解释结构模型化(ISM)技术构建了粗粒土干密度影响因素的解释结构模型;通过系统分析,将基于WSR方法考虑到的11个影响压实试验中干密度的因素按照其影响程度分成了5个层次等级,并与在试验中的实践经验进行了对比。研究结果表明,在压实试验中,试验仪器的精确度、激振力、压重和激振时间对于粗粒土干密度的大小起着直接的作用,与笔者的实践经验是相似的。
The influencing factors on the coarse grained soil dry density in the compaction test were fully analyzed and summarized in this paper from multi-perspective views.The three aspects of physical attribute,external factors and test operation were considered based on the system engineering method,which is termed as Wu-Li Shi-Li Ren-Li（WSR）.The index system of the influencing factors on coarse grained soil dry density in the compaction test was established based on WSR.The interpretative structure model（ISM）of the influencing factors on the coarse grained soil dry density was presented using interpretative structure modeling technique.The eleven factors in the WSR model were divided into five levels according to the influencing degree. The results were compared with practical experience.The results show that the accuracy of the test instrument,vibration force,surface pressure and vibration time can directly influence the coarse grained soil dry density in the compaction test and the results are similar with that of practical experience.
