叠加载荷下地壳的变形被认为是结构力学中的一个问题。地壳被视为一个均匀的，弹性的，薄的，球壳，地幔被视为一个封闭的粘性液体。建立了荷载与地壳响应的关系式。载荷可以是空间集中的、局部分布的或全局的，并且可以作为稳态或瞬态条件施加。根据水库负荷，冰盖和海平面上升的地壳位移的预测和同意与观测的幅度和时间。特别是北美的威斯康星州冰川作用。
The deformation of the earth's crust under superposed loads is considered as a problem in structural mechanics. The crust is treated as a uniform, elastic, thin, spherical shell, and the mantle is treated as an enclosed viscous liquid. Equations relating loading and crustal response are developed. Loadings may be spatially concentrated, locally distributed, or global and may be applied as a steady-state or transient condition. Crustal displacements under reservoir loadings, glacial sheets, and sea-level rises are predicted and agree well with observations both in magnitude and in time. The Wisconsin glaciation in North America is treated in particular.
