Balancing-optimalizing method, for project time limit, quality and cost, used in concrete faced rockfill dam construction

Abstract

The invention belongs to the technical field of civil engineering, and provides a theoretical basis and a feasible, effective and practical method for an engineering decision, meanwhile, assists managerial staff of an engineering project in managing and controlling dam body filling construction; besides, the balancing-optimalizing method performs consideration from the whole life cycle of the engineering to comprehensively consider the important influence from the project time limit and the quality on the cost, and provides a construction scheme which more meets practical construction requirements and is more economical for decision makers. Therefore, the technical scheme adopted by the invention is that a balancing-optimalizing method, for the project time limit, the quality and the cost, used in the concrete faced rockfill dam construction builds a balancing-optimalizing model which is based on quality cost and decision preference, and gives a non-dominated sorting genetic algorithm which is used for optimizing model solution and based on fuzzy project time limit and fuzzy quality; a built mathematical model is a built objective function; a fuzzy measure Me method is adopted to calculate the project time limit, the quality, the construction cost and the total cost of each general scheme. Thus, the balancing-optimalizing method provided by the invention is mainly applied to the civil engineering.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to an equilibrium optimization method applied in the filling construction of a face rockfill dam. technical background [0002] The face rockfill dam has now become a relatively economical dam type recognized in the world. With the rapid development of pumped storage power plants in my country, face rockfill dams are increasingly being used in pumped storage power plants. The construction of face rockfill dams began in the 1850s, when an earth-rockfill dam covered with wooden panels appeared in the gold mining area of ​​the Sierra Nevada Mountains in California, USA at that time. After the 1970s, the face rockfill dam entered a modern development stage marked by thin layer rolling technology, and the rolling rockfill gradually replaced the traditional riprap. With the development of CFRD construction technology, there are more than 600 CFRDs proposed and unde...

Problems solved by technology

At present, the research on multi-objective optimization of construction period, quality and cost of dam projects mostly focuses on the model of a certain objective or the qualitative and quantitative constraint relationship between two objectives, often ignoring the relationship between construction period, quality and cost. and the quality indicators in the balanced optimization are artificially controlled by the supervision system, so it is difficult to keep the quality at a high level stably; at the same time, the real-time monitoring system is an advanced construction management method, which is not reflected in the current research. They ignore the important impact of real-time monitoring system on quality cost and construction control and management decision-making, and have certain limitations
