计算了在引力势差引起的力的作用下，地球岩石圈出现的全球应力场。提出了一种新颖的算法，并开发了可操作的地应力程序代码。计算中考虑了地壳和上地幔的地形、厚度和密度，以及岩石圈的重力异常和热条件。将计算结果与观测数据进行比较，可以得出结论：仅引力势差的作用力就足以解释地球岩石圈一级应力场的特征。
The global stress field appearing in the Earth’s lithosphere under the action of forces caused by the difference of gravitational potential is calculated. An original algorithm is proposed and the operational Earth Stresses program code is developed. The data on the topography, thickness, and density of the Earth’s crust and the upper mantle, as well as the gravitational anomalies and thermal conditions in the lithosphere were taken into account in the calculations. A comparison of the calculation results and the observed data makes it possible to conclude that the action of the forces of the difference of the gravitational potential alone is sufficient to explain the features of the first order of the stress field in the Earth’s lithosphere.
