Multi-attribute decision-making model for choice of the soft soil foundation treatment methods

摘要

In order to choose a reasonable treatment method for the soft soil foundation, the main factors which affect the soft soil foundation, including technical feasibility, economic rationality and environmental effect, are analyzed. Based on these key factors, a two-level evaluation factors structure for the selection of fare collection pattern is constructed. Taking optimal treatment method as the goal, key factors as attributes, and available methods as alternatives, a multi-attribute decision-making model is set. Under the situation of one case, the model is applied to determine the most suitable treatment method for the case. The best choice is deep mixing pile. The results show that the model is effective and reliable.
