根据白垩－第三纪红层中构造变形的实际观测及水系统计资料，计算了三峡地区新生代和新构造期分区（幅）及区域应力场的主应力方向。结果表明：主压应力为北东东向、主张应力为北北西向，现代构造应力场与新生代以来应力场基本一致。晚第三纪以来，该区地壳应力场趋于相对稳定和统一。
According to the actual observation of tectonic deformation in the Cretaceous-Tertiary red beds and the data of water system, the principal stress directions of the regional (regional) and regional stress fields in the Cenozoic and Neotectonic phases of the Three Gorges area are calculated. The results show that the main compressive stress is NE NE and the stress is north-north-west. The stress field of modern tectonic stress field is consistent with that of Cenozoic. Since Late Tertiary, the crustal stress field tends to be relatively stable and unified.
