Risk Management Research On The Construction Phase Of H High-rise Building

In the future,high rise building is the development trend of construction industy In recent years,the independent development of high-rise buildings is in the initial stage in China,and its experience is not rich enough.Compare with ordinary buildings,high rise building has many characteristics,such as arge-scale construction,long cycle,high-altitude operation and high labor intensity determine the inevitable uncertainty risk in the construction process.Due to the complex construction process,technology and organization management,the project construction requires higher strength continuity and higher quality safety,high-rise building projects than the general construction projects in the management of a greater risk characteristicsBased on the research object of the major hazard sources in the construction site of H construction project,the WBS method decomposes the whole engineering organization structure and the engineering operation structure,combines the risk management theory,takes the system safety theory and trajectory cross theory as the tool,and carries on the risk identification and risk evaluation of the major hazard sources in the construction process.helping the construction party to estimate in advance the likelihood of an accident and its impact,According to the safety risk assessment results to take appropriate preventive measures in advance,and put forward the construction safety control measures,to maximize the avoidance of safety accidents,reduce safety hazards,for the subsequent construction safety risk management of high-rise building projects in China to improve the safety risk management awareness and ability of the project construction parties,It is of great practical significance to strengthen its effective supervision and risk management of the project,reduce or avoid the possibility of safety risk accidents,reduce the loss of the project and successfully achieve the project objectives.
