| The construction machinery of in place site leveling is the main body of the construction engineering earthwork construction.The different mechanical combination schemes have different influences on the safety of engineering quality,the progress of the project,the construction cost and so on.Based on the characteristics of the site leveling construction machinery and the theory of multi index comprehensive evaluation,this paper puts forward a comprehensive evaluation model for the construction machinery scheme of the site leveling construction machinery by the research and improvement of the ‘AHP ’ and the autonomous decision-making comprehensive evaluation method.The evaluation model includes the evaluation index system,the acquisition and the pretreatment of the evaluation index system,the determination of the weight coefficient,the selection of the method of assembly.Through the comparison between the results and the new and old methods,the advantages and the feasibility of the method are described,and the value of the method applied to the practical engineering is demonstrated.On the basis of theoretical research,combined with the evaluation theory and software technology,the paper develops a set of software which has the function of optimizing the construction machinery scheme.The software has not only the construction machinery scheme optimization function,but also the construction scheme of site leveling project programing and other practical functions,such as earthwork volume calculation,which make it a versatile and practical site leveling special construction software. |
