Underground projects in the construction and implementation of the process is full of uncertainties ( risks) , its influence throughout the various stages of the project construction . In order to reduce the adverse effects caused by many factors of underground projects , early in the implementation of the project , system risk analysis , so that the back is given for its major risk circumvent policies and concrete measures to prevent them thoroughly . Thesis aims to provide a risk analysis method allows the owners to make a general analysis of the risk of the project , in the early stage of the project will be able to work out preventive measures as soon as possible ; also can make the contractor on the project early in the bidding risk analysis to decide whether to tender . Paper -based risk management theory , the main line to the risk management process , combined with the characteristics of the underground project implementation , system of risk identification , risk estimation , risk assessment connotation and the use of technical means , the risk of underground projects were analyzed. Paper 's innovation lies in : ( 1) analysis will be applied to other areas of the social factors introduced into the the underground project risk analysis , at the same time , will be used for general project risk identification methods, such as : the checklist method , WBS -RBS method , the fault tree method effectively applied to the underground project risk identification . ( 2 ) for the different risks in underground projects , using different methods ( qualitative , quantitative or a combination of both methods ) to estimate its size. ( 3) for the underground project risk evaluation index system . At the same time , the papers in risk identification , it is estimated that the underground projects , combined with a small instance of the application last adjustment of Guangzhou Metro Line project , for example , a comprehensive assessment of its risk from the contractor 's point of view , concluded .
