摘要

摘要: 在分析渤海构造演化背景和地质构造特征的基础上,根据区域内已有测点的地应力资料,建立渤海三维应力场优化反演分析模型。通过由有限元法得到的测点处应力值大小及方向与现场实际数据的比较,构建误差函数作为优化目标函数,采用Hooke-Jeeves优化算法与有限元计算相结合的方法进行优化反演分析,将ANSYS有限元程序作为一个计算模块并通过Matlab 实现其批处理模式下的循环调用,完成优化反演计算过程,得到了渤海浅部的现今应力场分布规律。优化结果分析表明,该文方法可以通过较少的测点数据优化反演得到较合理的构造应力分布,能够为进一步研究渤海海域现今构造活动提供一定参考。

Abstract: An optimization inversion model of 3D ground stress field of the Bohai Sea was established based on the in-situ stress data from the existing measuring points in the study area and the analyses of tectonic evolution background and characteristics of Bohai Sea. By comparing the stress values and directions obtained at measuring points by means of finite element method with the in-situ measured data, an error function was established and taken as the optimization object function. The optimization inversion analysis was carried out by combining the Hooke-Jeeves optimization algorithm and the finite element method. The optimization inversion calculation process was completed by taking the finite element analysis program ANSYS as a calculation module and calling circularly the batch model through the Matlab platform, thus obtaining the distribution law of the present shallow ground stress field in Bohai Sea. The research results have shown that the method presented in the paper can be used to inverse a more reasonable stress field distribution by using the data from less measuring points, thus offering a reference for further study of the tectonic activity in Bohai Sea.
