在混凝土坝中利用冷却水管中循环冷水来降低混凝土内部水泥的水化热温升，是混凝土坝温度控制的最有效措施。
The cooling pipe, using circling cooled water to reduce the heat of hydration in concrete DAMS, is the most efficient method for temperature controlling in concrete DAMS.
大体积混凝土的水化热不容易及时散发，内部温升将会很高，从而产生很大的温度应力，导致出现温度裂缝。
The hydration heat of massive concrete does not emanate easily, so the internal temperature will be very high which will generate high thermal stress, then the temperature crack will appear.
