Research And Development On A Simulation System Of A Dam Of Asphalt Concrete Core Wall Facing Engineering Construction

The construction of asphalt concrete core wall is a complicated task. At the same time, due to the construction of asphalt concrete core wall affected by climate, temperature, initial setting time of roller compacted asphalt concrete, paving and other hierarchical factors, And the heart wall construction period, the combination of construction machineries and so on has a crucial role in of the dam construction schedule.The subject is intended to rely on the project of earth-rock fill dam of asphalt concrete core wall in Chongqing guanyin cave, and make use of control theory, similarity theory, computer technology, simulation technology, object-oriented technology, and system theory and methods, through the establishment of a database (include the core wall structural parameters, the parameters of construction equipment, the pouring and filling quality of the core wall, control conditions of the construction, graphical data, etc.) and complex simulation modeling, and design and development of program, realize simulation,resulting output and display of roller compacted asphalt concrete core wall dam paving process. This paper mainly studies contents and result as follows:(1) Based on the principle of computer simulation technology, development Status and the basic steps of simulation, made the basic concepts of simulation of the whole construction process and configuration system of simulation, further research the basic theory and methods of the key technologies during simulation software development.(2) summarizing anti-seepage technology and construction technology of asphalt concrete core wall.(3) Analysis asphalt concrete core wall construction system, and establish the simulation model of asphalt concrete core-wall construction.Meanwhile, analysis and th list systematically simulation result to a report, and study the simulation results, then apply the simulation conclusions to practical engineering- the project of earth-rock fill dam of asphalt concrete core wall in Chongqing guanyin cave, provide a reasonable allocation basis and consultation for selection of the construction scheme and the rational allocation of machinery and equipment. Provide a powerful analytical tool for Analyzing the whole construction process comprehensively, accurately and fast. In order to achieve efficient use and scientific management of construction information, insure the progress and quality of the engineering construction.
