Study on Concrete's Temperature Control Measures for Inverted-Siphons during Construction Period
In view of the problem of concrete cracks during construction, the good effect of cracks prevention can be achieved if the timely and reasonable scheme of temperature control is selected. Under the 3-D FEM including water-pipe cooling is adopted to simulate the stresses field of Inverted siphon during construction. Through analyzing the time-space variation law, it is fund that cracks easily appear. In the part of the middle line of the South-North Water Transfer Project£¬the quality of concrete surface of III section in Jiaozuo has been improved obviously through the method of external insulation board.
