Optimization for Determination of Parameters for Prestressed Cable Design

ZHANG Faming et al.[  
In hydroelectric project construction, usually, the stability of unstable slope is improved by prestressed cable (bolt). However, up to now, the design of prestresed anchor was rather conservative, leading to over consumpion in engineering. So there is a need to have more study on theory and method of anchor design. Based on analysis of factors influencing the design parameters with application of theory of optimization and decision, a method for determination of parameters for rock bolt design is suggested. A decision supporting system RSASYS for rock bolt support design has been set up, which can provide a new method for rock bolt design. The practice shows that this method is feasible and gives great economical benefits. [
