Through　the　adiabatic　temperature　rise　experiment,　the　adiabatic　temperature　rise　of　concrete　with　hydration　time　was　recorded.　Based　on　the　maturity　degree　theory,　the　relationship　between　the　hydration　degree　of　the　concrete　and　the　equivalent　age　was　determined.　Then,　the　hydration　degree　prediction　model　of　the　concrete＇s　early　elastic　modulus　and　tensile　strength　was　established.　The　local　temperature　and　humidity　of　the　concrete　were　measured　by　the　shrinkage　experiment,　and　based　on　the　capillary　water　tension　theory,　a　temperature-humidity　prediction　model　for　the　early　shrinkage　of　the　concrete　was　designed.　According　to　the　ratio　of　the　creep　deformation　and　elastic　deformation　of　concrete　which　were　obtained　through　the　restraint　ring　experiment,　a　model　for　predicting　the　early　creep　coefficient　of　concrete　was　proposed.　Based　on　the　coupling　effect　of　＂hydration-temperature-humidity,＂　a　prediction　model　of　early　cracking　risk　coefficient　of　concrete　under　multifield　coupling　was　proposed.　Finally,　several　groups　of　slab　cracking　frame　experiments　were　carried　out,　and　the　cracking　risk　prediction　results　of　concrete　were　consistent　with　the　actual　situation,　which　indicated　the　correctness　of　the　early　cracking　risk　prediction　model　of　concrete.
