New method for identifying elastic modulus of concrete gravity dam

LIU Ying\|xi 1,2 , WANG Deng\|gang 1,2 , LI Shou\|ju 1,2 , WANG Hai\|ju 1,2 ( 1. Dept. of Eng. Mechanics, Dalian Univ. of Technol, Dalian 116024, China; 2. State Key Lab. of Struct. Anal. for Ind. Equip., Dalian Univ. of Techno  
Making use of the improved genetic algorithms, this paper identifies the elastic modulus of the body and the basement of the concrete gravity dam according to the displacement caused by the water load. Numerical example results show that this approach is workable and has strong noise\|resistant capability. It is needless to solve ill\|condition equations in this method. This approach has the property of overall convergence, and the inverse results are reliable.
