基于中国地壳应力数据库和哈佛大学矩心矩张量目录,给出了中国现代构造应力场。反演结果显示,最大主应力轴走向在青藏高原西部为近南北向,在华北为北东东向。在中国中部地区,最大主应力轴走向呈放射状,即北部最大主应力轴走向为北北东向,南部最大主应力轴走向为北北西向。本研究给出了几乎整个中国的构造应力场的具体参数,为地震预测和地球动力学研究中的应力场模拟提供了基础数据。
Based on the Chinese crustal stress database and the Harvard CMT tensor catalog, the Chinese modern tectonic stress field is given. The inversion results show that the direction of the maximum principal stress axis is nearly north-south direction in the west of the Qinghai-Tibet Plateau and north-east direction in the north China. In central China, the axis of maximum principal stress is radial, that is, the axis of maximum principal stress in the north is north-north east and the axis of maximum south-principal stress is north-north-west. The study gives the specific parameters of the tectonic stress field in almost all China and provides the basic data for the stress field simulation in earthquake prediction and geodynamics research.
