Paper Title:
Studying the Rock Seepage Parameters Identification Method Based on Finite Element Method and Difference Evolution Arithmetic
  Abstract

The seepage of rock and soil is a common problem in geotechnical engineering, because of the uncertainty property of rock and soil, how to ascertain the seepage parameter of rock and soil becomes a problem to solve. Aiming to the problem, after introducing the theory of seepage parameter identification, the paper combines unstable seepage finite element method (FEM) and difference evolution (DE) arithmetic, constructs intelligent identification FEM method of seepage parameter, and develops the procedure. The hydraulic head distribution of seepage field can be calculated accurately by FEM and the optimal solution can be obtained by DE, the seepage FEM being embedded in DE, overcoming the local optimization problems of conventional methods and improving the precision of identification. A tam sample is calculated by the method, it states that the convergence speed is quick and result is satisfied. It is a powerful method for seepage parameter identification.
