In order to
evaluate the potential hazard of ShenzhenZhongshan Link tunnel
construction, an evaluation model of potential hazard of underwater tunnel
based on mutation theory is established. The evaluation index system is
improved by factor analysis so as to reduce the influence of subjective factors.
Seventeen safety potential hazard indices are sorted out according to expert
opinions, and 5 first level indices of potential hazards, i.e. floating
installation of immersed tube element, deep foundation pit excavation, immersed
tube structure prefabrication, environment and climate and offshore auxiliary
construction, are extracted by factor analysis, so as to build a hierarchical
safety hazard index system. By calculating the importance of each index to the
construction safety of the underwater tunnel and sorting the results, it is
found that the environmental and climatic hazard and the excavation hazard of
the deep foundation pit have the greatest impact on the construction safety of
the tunnel. It can provide the basis for the construction enterprises to
formulate corresponding safety control measures, so as to effectively prevent
the occurrence of safety accidents.
