Abstract

In this work, we perform reconstruction of elastic stress fields by employing discrete data on the principal directions of the stress tensor in Central Asia. The methodology assumes optimization of the deviation of the calculated and field data, as well as the continuity of the stress vector across a geological fault, in the case when it is explicitly taken into account in the model. The fields of the stresses trajectories and the maps of the maximum shear stresses are constructed for two regions. The example shows that the stress fields in the vicinity of the fault calculated in the model that takes the fault into account explicitly differ significantly from the stress fields in the model that does not take into account the fault.

基于主应力轴方向的中亚地壳弹性应力场建模

摘要

在这项工作中，我们通过使用中亚应力张量主要方向上的离散数据进行弹性应力场的重建。该方法假设在模型中明确考虑到的情况下，优化了计算数据和现场数据的偏差，以及跨地质断层的应力矢量的连续性。构造了两个区域的应力轨迹场和最大剪应力图。该示例表明，在考虑了故障的模型中计算出的断层附近的应力场明显不同于未考虑故障的模型中的应力场。
