The Application of the System Parameter Fusion Principle to Optimization Analysis of Bracing Systems for Deep Foundation Pits

摘要

The optimization analysis of bracing systems for deep foundation pits is a rather complex problem of system engineering which relates to many indexes belonging to safety and feasibility, economy and rationality, environmental protection and convenience of construction. In this paper, the evaluation index system of bracing systems for deep foundation pits is established; every index's overall sorting weight is determined; the comprehensive evaluation results are obtained to evaluate the degree of superiority and inferiority of bracing schemes by means of the system parameter fusion principle; and then the optimum scheme is concluded.
