摘要
大陆岩石圈有效弹性厚度(T_e)是表示岩石圈抵抗挠曲变形能力的参数。通过计算该参数,可以获得不同地区、不同构造省的岩石圈挠曲强度,并可以进行区域的比较。本文详细地介绍了T_e的计算方法、研究模型和控制因素。由于T_e与岩石圈热结构、流变结构、力学结构紧密相关,T_e的研究不仅有助于岩石圈强度的定量认识,而且可以获取岩石圈热结构、力学结构空间变化的信息,以及对地幔对流等动力学问题做出制约。
The effective elastic thickness (Te) is a useful measure of the integrated strength of the lithosphere to resist the flexural deformation. The Te values of various regions and tectonic provinces can be obtained, and a comparison from region to region can also be made. The methods , models and controlling factors of T, are introduced in this paper. Since it is closely related to the thermal, mechanical and rheological structures of the continental lithosphere, the study of Te is very useful to put constraints on them.
