Application of Information Entropy and FAHP Evaluation Model in Optimization Decision of Bracing System for Deep Excavation

Abstract:

The selection of bracing system for a deep excavation is a quite complex system engineering which relates to many target factors of safety and feasibility, economy and rationality, construction period, convenience of construction and environmental protection. In order to avoid the casualness in determining subjective weight by traditional fuzzy analytic hierarchy process evaluation, taking information entropy into consideration, the comprehensive evaluation model was established. This model is proved to be reasonable and effective by an engineering example.
