| With the advantages of simple structure,local materials,simple construction and low cost,the concrete faced rockfill dam has become one of the most widely used dam types in contemporary large-scale hydropower construction projects.During the construction of large-scale hydropower project,many problems are involved,such as the excavation of multiple material points and the filling of multiple parts of the dam,as well as the transportation of excavated materials and filling materials,material property matching and dam strength,etc.Earthwork allocation is one of the core issues of large hydropower construction projects,which is of great significance to the construction progress,quality and cost of the project.A reasonable earthwork allocation scheme plays a vital role in the smooth progress of the whole project.How to reasonably plan and formulate the earthwork allocation scheme under the influence of various factors in the project is a problem of great concern to the current engineering and technical personnel,which has important research significance.Aiming at the difficulty of earth rock allocation of a concrete faced rockfill dam,the traditional method is improved on the basis of comparing and selecting the relevant solutions.The system analysis method is adopted,and two global optimization bionic algorithms are used to solve the problem.In the aspect of mathematical model,through the systematic analysis of the background data of the concrete faced rockfill dam of the upper reservoir of a pumped storage power station,this paper uses the theory of dynamic programming,takes the lowest total allocation cost as the goal,deeply and carefully considers various constraints in the actual construction,so as to enhance the accuracy of the model.In the aspect of program,based on Microsoft Visual Studio C # language,the software of earth rock allocation system for the concrete faced rockfill dam has the advantages of simple operation,friendly interface and strong applicability.The results of two allocation schemes are obtained through software calculation,and the optimal earth rock allocation scheme is determined by comparison.The rationality and practicability of this study are verified by practical engineering. |
