Establishment And Application Of Intelligent Feedback Optimization Method In Tunnel Construction Based On Harmony Search Algorithm

Affected by the parameters with complexity and uncertainty of rock and soil, construction design and construction safety of tunnel engineering are often overly dependent on experience, resulting in unnecessary loss of property and casualty. But the traditional optimization method has some disadvantages such as complex theory, too many control parameters, the lengthy calculation process, difficult operating procedure, which makes it difficult to get wide application in practical engineering.Hence this text does the research on the Intelligent feedback optimization model with perpendicular method, numerical computation method, regression fitting method,Harmony intelligent search algorithm and combined with the construction site monitoring displacement, and sets up the intelligent feedback optimization method of rock soil parameters and construction anchoring parameters based on this algorithm. Afterwards, optimize the parameters of the construction and study the operating procedures of the method under different conditions of construction taking Fusong tunnel project, Dalian Metro Lot100Academy Square Station Project, Dalian Metro Lot202Dong Wei Lu Station to Spring Street station interval shield tunnel construction projects as research objects.Finally, get the optimization results through the studying of the three projects, and compare with the actual project, discuss the optimization results. Then evaluate the applicability and reliability of this optimization method in geotechnical engineering according to this result.
