The surface loading of the mountains and the associated root of thickened crust produce horizontal deviatoric tension in the strong upper crust. in contrast, the deep, dense lithospheric root and its associated downflexing of the surface produce horizontal compressive deviatoric stress in the strong near - surface layer. the actual state of stress in the strong layer of the upper crust is the combined effect of these two opposite stress systems together with bending and other local and regional stresses such as due to ridge push
模擬結果表明：由於均衡機制，造山帶下部的低密度山根促使地殼隆升、造山，山根是地殼剛性層中張性構造應力的主要力源；與此相反，冷的高密度巖石圈向軟流圈插入、拆離、下沉，從而形成巖石圈根，它引起擠壓造山和巖石圈地幔物質的重新調整，也是地殼剛性層中擠壓性構造應力的主要力源。 -
