摘要
针对日益丰富的数据资料 ,综述了大地测量反演的发展进程 ,论述了多种数据联合反演的意义和必要性 ,给出了兼顾权比确定的大地测量、地震和地质三类数据的联合反演模式及采用水准测量、GPS和重力三种数据联合反演断层参数的具体公式 ,特别介绍了求解优化问题所有全局最优解的区间算法 ,并给出了基本算例 。
The progress of joint inversion in geodesy and geophysics are summarized in this paper. The significance of joint inversion with numerous and high quality data is discussed. Two formulae of joint inversion, which are based on mechanics with geodetic, seismic and geologic data and on dislocation with leveling, GPS and gravity data respectively, are given. And especially, the relative weight ratio can be determined during inversion. Interval algorithm that can find all global optimization of object function is mainly recommended and two examples are given. The results show unexampled superiority and prospect of interval algorithm in application in geodetic and geophysics inversion.
