不同环境温度下混凝土箱梁的温度分布及演化规律
Temperature Distribution and Evolution Law of Concrete Box Girder under Different Ambient Temperatures
摘要
Abstract
By considered the temperature difference between the inside and outside , outer surface layer and environment of the mass concrete in different regions , seasons and temperatures , the variation of the temperature field distribution and the variation of the 2 kinds of temperature difference of 32 m single box single chamber prestressed concrete box girder were discussed , midas was used to simulate the effect of environmental temperature variation on concrete box girder , the evolution characteristics of the 2 kinds of temperature difference were discussed .The results show that , when the temperature difference between day and night is greater than 10 ℃, the temperature difference between the inside and outside , outer surface layer and environment of the concrete can be changed significantly .According to the simulation results , arrangement of temperature measurement points is designed based on the change of environmental conditions , the distribution and evolution of temperature field of concrete box girder under different environments are revealed .关键词
