Abstract


Concrete faced rockfill dam due to its outstanding advantages such as economy , short construction period , thus increasing proportion of the dam Especially in the field of the high dam , the number of rockfill dam is more than a concrete gravity arch dam , majority status . Panel Rockfill dam construction is CFRD construction of the core is a complex system engineering , and construction aspects of more complex construction environment , hydrology, meteorology, topography, geology , and many other factors limit the construction process , the existence of various uncertainty factors . Risk exists in the construction stage , the various links throughout the project the whole story . However , due to the lack of knowledge of risk , risk management ineffective and cause and Rockfill dam construction engineering problems are common . Therefore, in order to play to the advantages of rockfill dam , so that the rapid construction , it is necessary for a specific project for a certain amount of risk analysis and risk management . In this paper, the Gongboxia concrete face rockfill dam filling the actual construction , the use of risk analysis methods to identify one by one , first of all risk factors on the impact of filling in the construction of this system ; based on risk , the use of fault tree analysis method , the influence geological risk ( uncertainty ) dam material construction , flood , rainfall , transportation risk , risk analysis research , collect data , establish the uncertainty model of construction risk factors ( events) may occur and may cause consequences for qualitative or quantitative description . In this paper, the dam material uncertainty , decision tree analysis model of the three options , screening , recommended the third program . The actual construction of this program , to prove that the model has a certain practicality and reliability . Based on the above analysis , the use of risk coping strategies, the filling construction risk prevention Gongboxia rockfill dam concrete measures . Filling construction risk prevention and rockfill dam in the general sense to provide a reference .
