摘要
岩石开挖工程涉及到生产和生活的各个方面,随着社会需要和科技进步,岩石开挖工程的规模越来越大,因而正确评价岩石工程的状态更加重要。详细地分析了岩石工程评价中的多种不确定性因素,介绍了岩石工程随机分析的基本原理,提出了进行岩石工程随机分析的4个基本观点,通过实例介绍了岩石工程随机分析理论的应用以及对工程的指导作用。
In our production and life, there is a lot of rock excavation projects. The engineering size is bigger and bigger as the society needs increase and science and technology advance. Therefore it is more important to correctly evaluate the conditions of the rock engineering. This paper analyzes many uncertain factors in detail, such as the uncertainties of rock strength, joint distribution, rock layer, load, failure model etc., introduces the basic stochastic analysis principle of rock engineering, and proposes the 4 viewpoints on the rock engineering stochastic analysis. Rock failure is a progressive process. Rock mass is a spatial random medium, rock engineering is three-dimensional. Rock mechanics is a system engineering. At last, the 2 examples of rock slopes are given on stochastic analysis of the rock engineering.
