Study on Temperature and Stress Development of Channel Lining Concrete in Construction

Abstract:

Lining of water transportation channel needs high requirements of crack prevention. The tension stress which results from temperature and other factors during construction is an important reason that causes concrete cracks. Through the simulation of concrete lining during construction period with a section of the middle route of South-to-North Water Transfer Project, it is found that concrete pouring temperature, joint space, cutting joint time always make great contributions to lining crack. Based on calculation results some pertinence measures for temperature control and crack prevention are put forward. Engineering practice shows that effects of these measures are remarkable, which means these measures have significant reference to the concrete lining construction of the same type channels.
