本文提出结构面、构造力学韵域体、构造体系和构造体系共生带,是认识构造变动全过程的四重基本概念。作者强调从结构面入手,抓认识构造断裂三项基本要素:即结构面形态及蚀变程度、应力岩、应力矿物和应力矿物现象,运用构造形变与岩矿相变相结合的方法,准确地鉴定结构面的力学属性。 作者运用此理论于三峡三斗坪坝址,找出了坝址构造形迹的展布规律,准确认识了岩体结构类型展布规律及水文工程地质条件。
This paper proposes the four-fold basic concepts of structural plane, mechanics rhyme domain, tectonic system and structural system symbiosis belt. The author emphasizes that starting from the structural aspect, we should grasp the three basic elements of tectonic fracture: the morphology and alteration of structural planes, stress rocks, stress minerals and stress minerals. By means of the combination of tectonic deformation and rock-mine transformation, Mechanical Properties of Structural Surfaces. The authors apply this theory to the Sandouping dam site of the Three Gorges Dam to find out the distribution rules of the dam site structural features and accurately understand the distribution regularity of the rock mass structure and hydrological engineering geological conditions.
