| 摘 要： | 在对仿真退火算法研究的基础上,将非常快速仿真退火的连续模型空间改为可变的离散化形式,理论模型试算表明,使用本文方法可提高工作效率5-10倍. 为适应联合反演的需要, 对非常快速仿真退火的误差"单判断"检验准则改为误差"双判断"检验准则,避免Metrop olis接受准则的判断失误. 在此基础上,实现了一维及二维起伏地形条件下大地电磁与地震资料多参量信息的联合反演. 理论模型的试算及实例说明了约束联合反演的有效性.

| Abstract: | In this paper the continuous model space of the very fast simulated annealing was transformed to a variable discrete. It can be proved by theoretical models that 5 to 10 times calculation workload can be saved. In order to fit the needs of joint inversion, the 'single judge' rule in the error checking of the very fast simulated annealing algorithm was developed to the 'double judge' rule to avoid the judge mistakes made by Metropolis accepting rule. One dimensional and two dimensional multi parameters joint inversion of magnetotelluric and seismic data were put forward under the uneven topography conditions. The example calculation results of the theoretical models and real observed data illustrated that this constraint joint inversion technique was quite effective. |
