The Optimization Of Construction Site Layout In Water Resources And Hydropower Engineering

Abstract: The construction site layout is an important and complicated matter in construction organization arrangement of water resources and hydropower engineering because of its plentiful influencing factors and numerous contents. The thesis have a study on the three dimensional design of facility layouts the optimization choice of important facility and the scheme selection optimization of construction site layout.The three dimensional design of facility layout is based on the digital terrain model, by comparing with the characteristics of rectangle network and triangle network, this paper set up the digital terrain model. The calculation of earthwork excavation, the design of deserted spot and the design of constructional spot are completed on the basis of the DTM and the three dimensional model of earthwork excavation are displayed. At the same time, the paper expound that the ruled surface are use to represent the three dimensional model of constructional road.Concrete production system should be put emphasis on the construction site layout in the construction of concrete dam. The relation of the subsystem in concrete production system is strong, so the location choice is involved in several factories. With the aid of mathematical model of logistics center choice, the thesis set up the transportation model among the buildings stones of sand fields, machining factory, the concrete stir system, the concrete pouring system. Put the Linear Interactive and Discrete Optimizer software into application to solve the transportation model, we can get reasonable location choice and material transportation project.By analyzing the abutting relation among facilities, the initial construction site layout project is making. In consideration of the actual situation in decision making of location choice, the fuzzy exists in the plentiful influencing factors and decision-making process should be attached importance to. This paper applies the fuzzy theory and the newest decision-making theory to the process of construction site layout scheme selection optimization and set up the fuzzy-attribute decision making of construction site layout selection. Finally, an example is given to show concretely the decision-making process.
