摘要
Abstract
The granitic rock mass existing in shiplock zone of the Three Gorges dam contains a number of major discontinuities, of them one hundred and thirty three major discontinuities have been mapped around the shiplock covering an area of 1740×600m. These major discontinuities were analyzed by using block theory . However, it is important to keep in mind that discontinuities are finite and some key blocks are actually infinite blocks. In this paper, a stochastic model is incorporated into the key block theory to study the slide probability of key blocks on the high slope of the Three-Gorges of the Yangtze River, and the size and density distribution of blocks are also analyzed. The results provide a theoretical basis for the reinforcement of the high slope on the Three-Gorges of the Yangtze River and are of great significance in engineering practice.关键词
