Simulated Calculation of Temperature Control and Anti-crack during Construction of Inverted Siphon

Inverted siphon, such a thin-walled structure, tends to have large internal and external temperature differences during the early stage of pouring, resulting in a large tensile stress on the surface. Once surface or penetrating cracks appear, it will have a great influence on the integrity, safety, impermeability and durability of the structure and reduce the water transfer function. The temperature control simulation of the Liyanghe inverted siphon in the middle line of South-to-north Water Diversion project was designed to select the temperature control measures of inverted siphon concrete during different month construction. Temperature control measures can provide references for similar projects at home and abroad.
