Study On Computer Simulation Of Dam Concrete Pouring Construction In Xiaowan Project

In the concrete-dam construction process, there are many uncertainties influencingthe construction process, which results in the low efficiency of construction machines.Therefore the concrete-dam construction is a complicated system. In order tocomplete the construction project on schedule, it is necessary to make the rightscheme of machines deployment, evaluate the effect of actual construction, analyzethe factors influencing construction process, forecast the construction developmenttrend, and adjust the construction plan of later works, manage and control theconstruction process effectively. This paper studied the questions as follows. Firstly, in order to model the concrete-dam construction process, theconcrete-dam construction system has been analyzed using simulation theory. Basedon the system theory, the concrete-dam construction is a big system. Analyzing ofactual condition of concrete-dam construction system, the systems objectives weredetermined, the system's structure and function of each structure was defined, therelation between structures was revealed, and then a simulation model ofconcrete-dam construction system was presented. We applied the object-oriented method (OOM) to established the simulationmodel of Xiao Wan construction system. The object-oriented method (OOM) is inaccord with the manner in which mankind understand the world. The conceptions ofOOM such as object, class, inherit and enclose are close to the reality and which makethe modeling process easy. After the system analysis of the construction in Chapter 2,we restudied the modeling of concrete-dam construction system, establishing a modelof concrete-dam construction system simulation based on the object-oriented method,which overcome the shortage of traditional structural method. We analyzed the formula of the crane machine's workflow and the superpositiondegree using in conflicts control when many cranes machine working together.Abundant Intensity is defined and some characters of the conception is revealed. Thensome discussions are made in the relation between the superposition degree andabundant intensify. Xiao Wan Dam Construction simulation system's design principle, designmethod, system structure, modeling approach and data organization are also specifiedto some extent. Xiao Wan Dam Construction simulation system application is developed. Weused the Xiao Wan project as an example to test the application. The simulation of theconstruction process is done and the simulation result has been analyzed in detail inthis paper.
