It is studied the temperature stress of an overlength basement concrete structure in Shenyang by finite computing software.It is also explored the characteristics of temperature stress of the base board,floor and exterior wall with and without the post-pouring strengthening band.And four schemes are put forward to control the temperature stress of the second construction stage.The results show that the temperature stress of the basement with the post-pouring strengthening band according to the schemg decreases obviously.The conclusion shows that expansion joint may not be set on the overlength basement through setting the post-pouring strengthening band and temperature shrink reinforce ment reasonably,adopting the shrinkage-compensating concrete,adopting the fourth scheme to control the second construction stage,along with doing a good job in temperature difference,materials,production technology of concrete and construction.
