人机联作方法与最优化方法是重磁异常反演中常用的方法。利用人机联作进行反演,使用灵活、适应性强,物理意义明显、反演过程易于控制。最优化方法则是一种能够自动迭代、拟合精度较高的反演方法。我们将这两种方法联合使用,称为人机联作最优化反演方法。它具备了一般人机联作与最优化方法的优点,同时又弥补了它们各自的不足,简化了反演过程中数据准备工作。我们在利用该方法进行重磁资料反演时,通常在人机联作时给出初始地质体模型,通过调整模型参数,对实测异常拟合,其精度由人来控制,在这里所需要的是异常形态及其幅值的满足。然后由最优化反演过程进行自动迭代反演,从而得到拟合程度较好的反演结果。
Man-machine cooperation method and optimization method is commonly used in gravity and magnetic anomaly inversion. The use of man-machine cooperation for inversion, the use of flexible, adaptable, obvious physical meaning, the inversion process is easy to control. The optimization method is an inversion method that can automatically iterate and has high fitting accuracy. We use these two methods together, called the man-machine cooperative optimization inversion method. It has the advantages of general human-computer cooperation and optimization methods, and at the same time makes up for their respective deficiencies and simplifies the data preparation in the inversion process. When we use this method to perform gravity and magnetic data inversion, we usually give the initial geologic body model when the human-machine interaction is in progress. By adjusting the model parameters and fitting the measured anomalies, the accuracy is controlled by people. Is the abnormal morphology and amplitude to meet. Then the iterative inversion is performed automatically by the optimal inversion process to obtain the better inversion result.
