Problems solved by technology

[0003] Most of the accumulations are composed of uneven blocks. The traditional analysis method for the stability of accumulations is the limit equilibrium method. In numerical modeling, the blocks composed of them are usually simplified into homogeneous bodies. This method ignores the Influenced by the shape, which is not consistent with the site conditions, resulting in a certain deviation in the calculation results, which cannot better meet the needs of slope engineering construction; therefore, it is urgent to invent an effective method for the stability analysis of accumulation bodies. On the basis of the distribution shape, the real simulation of the composition of the accumulation body is realized

Abstract

The invention discloses a method for establishing a numerical calculation model of an accumulation body slope using a stone-catapulting mechanism. By selecting a typical part of an accumulation body, a digital camera is used for image shooting to collect a batch of rocks; Extract and build a block library; then according to the size of the accumulation body provided by the survey data, use the catapult mechanism to build a real calculation model of the accumulation body; finally convert it into a graphic interactive file, and construct the model data of the corresponding geotechnical material for analysis calculate. In this design, the real calculation model of the accumulation body is constructed by constructing the block library, and then calling the block stone library data and randomly placing blocks to realize the real simulation of the composition of the accumulation body, which can effectively improve the accuracy of the calculation of the stability of the accumulation body, and in addition to In addition to calculating the stability coefficient of the accumulation body, it can also obtain relevant information parameters such as the stress and strain of the accumulation body, which has good practicability and promotion prospects.

Description

technical field [0001] The invention relates to a method for establishing a numerical calculation model of an accumulation body slope using a catapult mechanism, and belongs to the technical field of slope protection. Background technique [0002] Accumulation is a concept based on genesis and properties of rock and soil. It refers to the geological body formed by the accumulation of loose and broken rock and soil. It belongs to the product of continuous movement after deformation and destruction of slopes. This kind of accumulation body is usually in a critical state in the natural state, but due to the disturbance of its excavation during engineering construction, the original topography and landform are destroyed, and the original balance state of the slope body is changed, which easily leads to the stability of the accumulation body problems, which bring troubles to the construction of the project. [0003] Most of the accumulations are composed of uneven blocks. The tr...
