Experimental Research on the Temperature Field of High and Hollow-Thin Pier

Abstract:

To study the temperature field changing regulation of hydration heat and control concrete cracks caused by great temperature difference in the construction of hollow-thin pier, testing the temperature field of the high and hollow-thin pier of Cha Jiugou Bridge and it got changing regulation of the temperature. The finite element analysis on the pier was also carried out and the temperature stress contours and curves of the hydration heat of the concrete are obtained. It can be seen that the outer surface and the center of the pier are compressive within 10 hours in the pouring early. With the temperature difference, the center generates the compressive stress, the surface generates tensile stress.
