The Siting Of Prefabricated Beam Field And Production Optimization Of Large Construction Projects

With the gradual improvement of the socio-economic development and building technology, more and more large-scale projects on the construction schedule. In the process of building large-scale construction projects, the production of precast beams in many projects of the project plays a vital role. Precast beam as a production base for precast beams, the location and layout in addition to a direct impact on production activities to a certain extent, also the economic benefits of the engineering units, the conservation of national land resources, and many other factors have a direct impact. Site selection in the beam, the beam field site in accordance with the scientific field of the beam location principle, can be conducive to the smooth production, but can also facilitate the subsequent use of precast beam transport and many other areas. The key factor in decision to the internal production of the beam field is the internal layout of the beam field, the internal layout of reasonable scientific optimized beam field, especially within the beam field beam station optimized settings, optimize the layout of the core within the beam field. In modern engineering practice, most of the beam field in the location and layout are to comply with the traditional experience-based layout method, this method is in the effect of the experience of a large number of the test of practice to meet the basic requirements, but in many details by the optimization of science there are a lot of room for improvement.Projects now have a huge impact of the project, project volume, project complexity, higher requirements on the controlling node works, the traditional location and layout of this time in many places can not do, Therefore, to find a scientific and rational optimization method, it is necessary to optimize the beam arrangement. On the basis of in-depth study of relevant literature, start with the peripheral beams of the overall site to proceed, first discussed the precast beam the location of the problem, introduced precast beam field site type based on the analysis of the precast beam the field site location principles and site play an important factor. And then into the core of this paper, the beam field of the large construction projects, layout design and optimization, from the theory, under the premise that there is sufficient theoretical basis, the optimization design of the beam field layout of the large-scale construction projects to establish the corresponding optimization model, in order to test the model the effectiveness of selected Wuxi East beam field application test model as an example, results show that a certain degree of improvement than the traditional layout of methods through the beam field in the model optimized layout, in reality, is feasible and effective.
