船坞底板大体积混凝土温度场及应力场仿真分析
Simulation analysis on temperature field and stress field in mass concrete of dock floor slab
摘要
Abstract
Based on the heat-conduction equation and stress increment equation, the temperature field and stress field in the concrete of the floor slab of a dock placed with the interval of 7 d is calculated and analyzed through ABAQUS finite element analysis after 90 d of its placement. The result shows that the placement scheme of placing in four layers with the interval of 7 d can meet the concrete anti-cracking requirement concerned.关键词
