The Urban Road Soft Foundation Treatment Scheme Evaluation Model Based on the Multiple Attribute Decision Making Theory

The Soft foundation treatment is a problem to be solved in the urban road construction. However, the evaluation of the urban road soft foundation treatment scheme is not standardized and unified. Therefore, it is of great significance to strengthen and standardize the study of the urban road soft foundation treatment scheme. In order to determine the optimal urban road soft foundation treatment scheme, the paper carried out the evaluation research of the urban road soft foundation treatment scheme. By analyzing the principle and applicability of the typical urban road soft foundation treatment scheme, the common knowledge base of the urban road soft foundation treatment scheme is formed. It has a certain reference value for the primary treatment of the urban road soft foundation treatment. By consulting a large number of research data, the workflow of the urban road soft foundation treatment scheme evaluation is established. Based on the engineering experience and considering the factors that influence the selection of the soft foundation treatment scheme, the evaluation index of the soft foundation treatment scheme is put forward. In the paper, the analytic hierarchy process(AHP) is used to determine the weight of the evaluation index of the urban road soft foundation treatment. Combined with the evaluation index and the corresponding weight, the evaluation model of the urban road soft foundation treatment scheme based on the multiple attribute decision making theory is established. The research results of the paper can provide reference for the decision of the urban road soft foundation treatment scheme.
