THE DEVELOPMENT CHARACTERISTICS OF THE FISSURES OF LIANZIYA HAZARDOUS ROCK MASS AND ITS DYNAMICS MECHANISM IN THE THREE GORGES DISTRICT OF THE YANGTZE RIVER
长江三峡链子崖危岩体裂缝发育特征及其形成动力学机理

In this paper, the authors have applied geomechanics to summation of the spatial distribution and arrangement of fissures in the Lianziya hazardous rock mass, based on the fundamental characteristics of fissures following antecedent structures and feature of different types of networks formed by fissures. Moreover, the paper has also put forward a new dynamics mechanism to hazardous rock mass in the area. The hazardous rock mass is considered to be formed by stress release gravity pull, which resulted from the combination of main free gravitational tendency caused by coal mining, secondary gravitional tendency of inclined ground, and vertical gravity.
