ofthe infinite seawater above,plicated surrounding rockand the difficulty in geological exploration,it is hardly to obtain the geological andhydrogeology situation of submarine tunnel engineering before the construction,inwhich there are many uncertainties,once the risk accident occurred,it WOuld bringserious losses,which are from a construction period delay and investment increase to agreat disasters.It is important to establish the risk assessment and control scienti6csystem of submarine tunnel in two aspects of theory and technology by further researchand systematic summarization.This paper relies on the Dalian Bay cross.sea channelengineering,researches on the security risk assessment and control countenTleasure ofthe large section submarine tunnel construction,the research achiev鋤ents aresummarized as follows.(1)This paper summarizes the basic concept and features of engineering risksystematically and puts forward the definition of the submarine tunnel constmction risk.And many conceptions such as the risk surroundings,the risk factors,the risk accidentsand the risk bodies are defined explicitly,at the same time,the features of the unnel security risk during the whole construction period,the basic trait,the influencingfactors and the control principles of core risk in submarine tunnel constIuctions and mespecific processes and methods of risk analysis assessment have also been proposed inthis paper,based on these achievements,the risk analysis assessment model and the eptance criteria are established.(2)The consequences of water inrush risk in submarine tunnel construction aredivided into life loss,society loss,surrounding influence loss and economic loss(whichinclude the direct and the indirect economic loss),the extension engineering method isused in analyzing the water inrush consequence severity in the F 1 weathered troughconstruction of the left line of the Xiamen subsea tunnel in this paper,and the problemthat the water inrush consequence severity loss cannot be considered unifiedly has beensolved effectively.(3)Based on the usual risk identification methods at home and abroad,according to therelevant data and the similar engineering data of the Dalian Bay submarine tunnel,bining the trait and difficulties of this project,this paper identifies the security riskof drilling and blasting method,pipe sinking method and shield driving method,萬方數(shù)據(jù)analvzes and evaluates the risks of drilling and blasting method’pipe sinking memodand shield driving method by using expert investigation,humericalcalculatlon andrel“ant en西neering data research,at last,the paper presents the prelim‘mary nsk繆adesassessment,spread out the likely fatal risks and puts forward the corresponding controlmeasures· 一(4)Rel啊ng on the Dalian Bay Subsea Tunnel,pr.ehensiveassessment of secufftyrisks of the two constmction methods,respectively corresponding to two pr0Jectfeasible pro伊砌mes,was carried out,the correspondingcontrol measures were alsoDut fo刑ard.At the same time,the concepts and features of core risk security have beenelaborated,the core risks of three different engiiaeering methods undersea tunnels haVebeen analysed.Thevarious impact factors 0f risks are classified on the basis ofextensive inVestigation and research on the j relevant engineering data, the rankevaluation matrix of each factor is obtained according tO membershiP functlon·Thelikelihood level and the severity level of the oonsequencesof risks are predlCtedbyusing the theory of the fuzzy mathematics and the Extension engineering·‘Ihen,ltcaIl beproved that the core risks of the program are eptable risks,but in the鼢1bleminim啪risk limits.Core risk control measures corresponding to three enganeenngmethods have been proposed. ..(5)Throu曲the analysis of each risk coefficient prehensive risk f-actor ot thealternatives,shield,pipe sinking method,drilling,it has been pointed out:Largecross.section subsea shield has such characteristics as uneven hardness,Poor tomatlonadaptability’high difficulty of the productionof machinery alld eqmpment lessexD耐ence,and technical risk,safety risk,economic risk are relatively large;Largecross.section imnlersed 劬e tunnel has such characteristics as large usage ofconstruction site,large destruction of underwater blasting on the the manneenvir0舯ent, great impact on the
