| 英文摘要 | We apply Genetic Algorithm to invert CSAMT data. Here, we invert both apparent resistivity and phase data which contain the near-field, transition zone field and the far-field without any correction. Genetic Algorithm is one kind of global optimization method with less dependence on initial model and more ability to find the best solution, but when the unknowns are too many then the non-uniqueness of solution is still a problem. When we use a multi-layer model in the inversion CSAMT does not yield a unique solution. In order to reduce the temptation to over interpret the data and to eliminate arbitrary discontinuities in simple layered models, we employ minimum structure to constrain the inversion result. We have defined minimum structure function for the CSAMT inversion based on genetic algorithm, and have found the optimal value of the Lagrange multiplier mu = 0.5. The designed models are H, A, K, Q and HKH, KHA. When the data is without noise or with 10% noise, the resulting resistivity models fit the true models well. When the data contains 20% noise, the inversion result is also good. The method has been used for field data processing, the result was good. Both synthetic and field data examples indicate that the method is effective. |
