摘要/Abstract

摘要： 构造应力是地壳构造运动最基本的力源之一, 地下流体及流体力在地壳中普遍存在并对构造运动产生重要影响。该稿讨论了地下流体、流体力和构造应力以及它们的概念与作用, 分析了流体力和构造应力的异同点: 构造应力是各种力源在地壳中产生变形而引起的应力的综合力, 流体力是流体存在和活动所产生的各种力的合力, 它们的力源主要来自地球内部, 内涵相互交叉, 大小不同, 但均能产生构造变动。

关键词: 构造应力, 构造运动, 地下流体, 流体力, 相互关系

Abstract: Tectonic stress is one of the fundamental forces, which cause crustal motion movement. Subsurface fluid and fluid force universally exist in crust, and there is important influence on the crustal movement. In this paper, subsurface fluid, fluid force, tectonic stress and their concept and action are discussed, the similarity and difference of the fluid force and tectonic stress is analyzed: the tectonic stress is a comprehensive one, which is produced through crustal deformation, and the fluid force is a resultant one, which is produced through fluid existence and activity. Their force sources are mainly originated from the interior of the earth, their different connotation and the size. However, they all cause tectonic movement.

Key words: Tectonic stress; Tectonic movement; Subsurface fluid; Fluid force; Mutual relation
