Study on the Temperature Field and the Crack Prevention Countermeasure During the Abutment Construction in the Middle East

Base on the concrete work of abutment belt conveyor bridge JIGCC project in Jazan, Saudi Arabia, finite element model hydration heat reaction during construction and maintenance period is established by taking actual field situation as input boundary condition. The verified temperature monitor data. It shows that curve good agreement with data, accurate enough. stress due to within allowable range, risk cracking under pouring scheme low. Further, influence factors are analyzed from aspects external surface insulation method, molding ambient temperature. Combined experience it put forward some crack prevention countermeasures mass Middle East.
