Optimizing generator socket construction schemes of Shuibuya Underground Powerhouse based on intelligent back analysis

JIANG An-nan(College of Traffic and Logistics,Dalian Maritime University,Dalian 116026,China)  
The generator sockets construction and the closely-related stability problem of lower side wall of Shuibuya Underground Powerhouse are key problems to solve in the powerhouse construction.Synthetically utilizing orthogonal design,three dimensional numerical simulation,genetic algorithm and support vector machine,the back analysis process for Shuibuya Underground Powerhouse is proposed.According to the process,using the monitoring data of upper sixth construction step,the mechanical parameters of surrounding rocks are back analyzed.Based on the mechanical parameters,the subsequent sockets construction schemes are numerically simulated and the optimal one is selected,so as to keep the stability of high side wall and generator sockets surrounding rocks.The optimizing result has guide meaning to the construction.
