The method comprises the following steps of: 1, acquiring engineering rock field structure initial data; 2, processing and extracting the engineering rock initial data; 3, constructing an engineering rock model; 4, identifying blocks and analyzing the stability; and 5, displaying the result. The method has the advantages that: the method realizes space modeling of the engineering rock slope and identification of key blocks, quickly identifies new structure surfaces in the engineering construction process, and can automatically search the key blocks, count the number and geometric information of the movable blocks and preliminarily calculate and analyze the mobility of the key blocks.

Description

technical field [0001] The invention belongs to the field of establishment and analysis of solid structure space modeling of rock mass engineering such as geotechnical engineering, mining, road engineering and water conservancy engineering, and in particular relates to a three-dimensional model of a rock mass slope and a block slide analysis method. Background technique [0002] Slope stability has always been an important research content in geotechnical engineering. With the vigorous development of national economic construction, there are more and more high and steep slopes in projects such as railways, highways, water conservancy and hydropower, and mines, and the problem of collapse is more prominent. In order to prevent the occurrence of geological disasters of collapse, it is more urgent to remediate the slope in a planned and focused manner, and to analyze the stability of the slope collapse. [0003] A large number of studies have shown that the occurrence of colla...

Problems solved by technology

[0004] Traditional analysis methods are based on numerical methods such as finite element, discrete element, boundary element and their coupling. It is difficult to consider the real characteristics of rock mass structure and engineering disturbance process in the simulation process. At present, block theory is mostly used to solve the above problems. However, there are still some deficiencies, such as the calculation of the size of the block without positioning the block, and the calculation of the stability of the block considering the effect of cohesion, etc.
