大陆岩石圈强度研究

岩石圈强度或有效弹性厚度(Te)控制着岩石圈对长期负载的响应及其演化过程和空间构型，包含丰富的地球动力学信息，对解译地壳、岩石圈乃至地幔介质的力学性质和动力学过程及机理具有重要的科学意义。本文拟回顾从均衡概念的提出至今关于岩石圈强度研究的发展历程，重点从历史角度梳理岩石圈强度研究的沿革脉络、各种方法发展的逻辑关联，并对岩石圈强度与壳幔耦合、岩石圈有效弹性厚度与地震孕震层厚度的关系以及岩石圈有效弹性厚度各向异性等问题进行初步探讨。

Research on the Strength of Continental Lithosphere

The strength or effective elastic thickness (Te) of the lithosphere controls its response to long-term loading, its evolution process and spatial configuration, and contains abundant geodynamic information, holding great scientific significance for the interpretation of mechanical properties, dynamic processes and mechanisms of the crust, lithosphere and even the mantle medium.We review the development of lithospheric strength research from the concept of equilibrium to the present, focusing on the historical dimension, combing the evolution of lithospheric strength research and the logical relationship between the development of various methods. The coupling between lithospheric strength and crust-mantle, effective elastic thickness of lithosphere and thickness of seismogenic layer, and anisotropy of effective elastic thickness of lithosphere are preliminarily discussed.
