| Abstract: | Engineers placed cooling pipes on the interior side of exterior walls to reduce hydration heat of fresh|pouring concrete,and this method decreased the temperature difference between exterior walls and the bottom board and controlled generation and development of cracks.In this article,authors introduce the cooling method used in construction of Shanghai exterior|circle cross|river sinking|pipe tunnel and evaluate its effect. |

| Keywords: | sinking|pipe tunnel cooling pipe temperature crack |
