摘要: Tunnel construction is a dynamic controlling system with observability and controllability; the feedback analysis requires identifying geophysics parameters adjusting supporting parameters, both of them are optimisation problems. The paper proposed nonlinear optimization technique based on difference evolution arithmetic (DEA), least square support vector machine (LSSVM), three dimensional numerical simulation. This method employs optimal architecture trained by arithmetic, instead time-consuming finite element analysis. Firstly, simulation used to create training testing samples for LSSVM model construction. Then relationship between rock or anchoring displacement constructed machine. Finally, obtained DE arithmetic. overcomes conventional shortages expending too much computing time easily being limited in local solution. was verified applying it Dalian Metro China, influence ability algorithm investigated.
