应用响应函数技术研究岩石圈挠曲

APPLICATION OF RESPONSE FUNCTION TECHNIQUE TO LITHOSPHERIC FLEXURE STUDIES

响应函数与弹性薄板挠曲模型均用于研究地球均衡,但二者的结合为认识岩石圈流变性提供了一种重要方法。本文着重介绍二十年来在这一领域的研究进展,并阐述了大陆岩石圈基本挠曲模型的多种改进(例如考虑非完全弹性、地下负荷、地形侵蚀等)及其结果。

Both response function and thin elastic plate flexure model are founded for studying the Earth's isostasy. The combination of them, however,represents an important way to understand the lithospheric rheology. This paper introduces the basic procedure, then places emphasis on a review of some main achievements in this area during the past twenty years, particularly, describes the necessities, algorithms and results of multiform improvements (e. g. , inelasticity, subsurface loading and topographic erosion) on the basic model of the continental lithospheric flexure.
