地铁车站叠合墙内衬早龄期温度与应变演化规律
Early-Age Temperature and Strain Evolution of Composite Wall Lining in Subway Station
摘要
Abstract
In order to explore the early-age temperature and strain evolution of the composite wall lining,on-site monitoring of the temperature and strain of the early-age lining wall is carried out based on the subway sta-tion composite wall project,and the crack distribution characteristics,temperature and strain evolution of the lining wall are analyzed.The results show that in the early-age,most of the cracks extend upward from the bottom of the lining wall construction joint,most of the cracks are vertical,and a few oblique cracks locate at the corner of the wall.The temperature in the middle of the lining wall is higher than the surroundings,the temperature peak and the temperature drop rate in the center of the wall are the maximum,and the surface temperature peak is the minimum,the obvious temperature difference exists bettween the in-inner and the surface.In the early-age,there are obvious expansion and contraction phenomena in the lining wall,and obvi-ous differences in the strain evolution in different directions.关键词
