Calculation method and system of rockfill concrete rockfill pile-up process

Abstract

The invention provides a calculation method and system for a rockfill concrete rockfill pile-up process. The method includes: establishing a three-dimensional model of an initial state of a rockfill block, wherein the rockfill block comprises a certain number of block rockfill bodies; analyzing the accumulation process and the final accumulation form of the three-dimensional model according to thefinite element / discrete element coupling analysis method. The finite element / discrete element coupled analysis method, which combines the finite element method to simulate structural stress and deformation with the discrete element method to track block motion, is called finite element / discrete element coupled analysis method. The method retains the advantages of finite element method and discrete element method, which can solve the kinematics and failure mechanics problems of multi-body. In the process of calculating the final accumulation form of the rockfill concrete rockfill block, thereare the characteristics of a large number of block rockfill bodies, complex stress and deformation of the rockfill body with the change of the stress. The mechanical analysis of the invention can completely depict the progressive accumulation process of the rockfill block under the action of the stress, and the calculation result is more accurate.

Description

technical field [0001] The invention relates to the technical field of construction engineering simulation, and more particularly, to a calculation method and system for the accumulation process of rockfill concrete rockfill bodies. Background technique [0002] Mass concrete occupies an important position in modern engineering construction, especially in water conservancy and hydropower engineering construction. More than 10 million cubic meters of large-volume concrete is poured in water conservancy and hydropower projects in my country every year. In addition, large-volume concrete is often used in ports, airport buildings, and heavy machine foundations. Rockfill concrete reduces the amount of cement by using a large number of rocks (particle size greater than 30cm), thereby effectively reducing the heat of hydration and reducing CO2 emissions. Low heat, easy temperature control, high construction quality, low construction cost and other characteristics, so it has broad a...

AI Technical Summary

Problems solved by technology

[0003] During the construction of rock-fill concrete, the accumulation process and final accumulation form of the rock-fill concrete have a great influence on the mechanical properties of the formed rock-fill concrete. However, due to the high cost of the experiment and the shape of the rock-fill body in the actual project The pattern is complex, so it is difficult to carry out more accurate experiments to analyze the actual project, so it is an inevitable trend to carry out numerical calculation methods to analyze and calculate the accumulation process of rockfill concrete rockfill bodies

But so far, how to accurately simulate and calculate the accumulation process and accumulation state of rockfill concrete has not yet had any results and methods for reference.
