OPTIMUM DESIGN OF ARCHED ROADWAY SUPPORT STRUCTURE

Abstract

Aimed at the optimum design problems of arch retaining structure, the concrete paper applies program building relevant arch retaining structural model, the simulation programs are based on the zero order optimization method. Section size as design variables, the maximum stress as state variables and unit minimum volume as the design objectives, the design parameters of arched retaining structure is optimized by simulation programs. This method can offer a theoretical basis for roadway supporting structure design.
