Temperature Field and Stress Field Simulation Analysis in Layer Pouring Mass Concrete of Dock Foundation

Based on exponential hydration heat model,three-dimensional finite element model of mass concrete is established by using software MARC.And then the life and death element is used to simulate concrete hierarchical pouring process.Taking hierarchical pouring project of #4 dock floor for an example,the temperature and stress field in intermittent time of 7 days are calculated.At the same time,it also analyzes the distribution and variation of maximum adiabatic temperature rise and the maximum principal stress for typical conditions.
