【摘要】：高速公路软土地基处理方案是影响工程质量、工程造价和建设工期的关键因素之一。为制定技术可靠、经济合理、安全适用的软基处理方案,提出采用反映属性特征值之间的统计参数——变异系数来计算属性参数的权重,系统研究了基于变权的高速公路软基处理范例推理智能评价方法。通过大量有明确结论的软土处理工程实例,建立软土地基处理方案范例库,用变异系数来确定属性参数的权重,采用Euclidean Metric Distance计算公式计算目标范例与源范例的相似性,找到与目标范例最为相似的源范例。实例分析结果表明,基于变权的软基处理范例推理智能评价方法具有较高的可靠性。研究成果将为制定科学合理的软基处理方案提供科学依据。
[Abstract]:The soft soil foundation treatment scheme of expressway is one of the key factors affecting the engineering quality, the project cost and the construction period. In order to make the soft foundation treatment scheme with reliable technology, reasonable economy, safety and application, This paper proposes to calculate the weights of attribute parameters by using the statistical parameter-coefficient of variation, which reflects the characteristic values of attributes. This paper systematically studies the intelligent evaluation method of case-based reasoning for soft foundation treatment of expressway based on variable weight. Through a large number of examples of soft soil treatment engineering with definite conclusions, a case library of soft soil foundation treatment scheme is established. The coefficient of variation is used to determine the weight of attribute parameters, the similarity between target case and source case is calculated by using Euclidean Metric Distance formula, and the source case that is most similar to target case is found. The intelligent evaluation method based on variable weight Case-based reasoning (CBR) for soft foundation treatment has high reliability. The research results will provide scientific basis for making scientific and reasonable soft foundation treatment scheme.
