Abstract Abstract:Research purposes ： Metro shield construction is a complex process， geological conditions have a major impact on the shield parameters. For the purpose of study the effect of geological conditions on the parameters of the shield，considering the stratums surrounding a certain section of a city tunnel， and the parameters that in different
geological conditions were converted into a complex network，this paper studied it from microscopic and macroscopic，
analyzed the evolution of the various parameters of the shield under different geological conditions. Research conclusions: (1) Verify the feasibility that transform shield parameter time series into complex networks;
(2 ) In different geological conditions interchange，parameters network ( s node degree significantly increased，indicating
that the shield system has greater volatility;( 3 ) Lithostratigraphic stratum is more stable than sand formations，and gas
compartment pressure is more sensitive to changes in the outside world， can be used to monitor the stability of the
system；(4)This study can provide support for the formation identification.
