Safety Risk Assessment Of Mechanized Construction Of High Rise Buildings

During the mechanization construction of high buildings,the construction machinery can transport a large number of personnel and materials,its can provide an irreplaceable contribution to solving the construction environment is poor,high-altitude operation,high structure,crossconstruction complex,and heavy engineering problemes.There exist many hidden accidents in the mechanization construction of high buildings,so the construction of high buildings safety management and accident analysis seem to be very important to analyze and predict them.In addition an evaluation model of mechanization construction of high buildings based on the rough set is designed,can provide safety risk decision basis for professionals,can ensure the normal construction of high-rise construction and workers life safety.The main research findings are summarized as follows:(1)Research on the development of high rise building construction machinery,find out the difference between the construction machinery and the construction machinery in the past few years.Through the investigation of Nanjing construction machinery to find out the relationship between the technical parameters and the number of casualties.(2)A lot of construction security accidents are analyzed in order to find out the highest risk of construction machinery types;based on the coding system,the analysis index of risk index literature is built;on the basis of the analysis of accident cases,get the initial table of the index system;the safety risk index system for mechanized construction of high-rise buildings of have been determined by applying Delphi method.(3)In addition an evaluation model of mechanization construction of high buildings based on the rough,determine the evaluation information table,discrete analysis of the indicators and reduce the analysis,obtained the evaluation information table after the reduction,So the index weighting and comprehensive evaluation value also be made certain.(4)According to the relevant laws and regulations to determine the scoring criteria,check and score the machine of Nanjing CBD,determine the evaluation information table,discrete analysis of the indicators and reduce the analysis,obtained the evaluation information table after the reduction,so the safety risk index weighting and comprehensive evaluation value of construction machinery is certained.
