The aging of concrete dam located on the regions with cold climate is characterized by resorption, destroyed by freeze-thaw and frozen-heave, scouring and etc. , but the carbonized depth is low.
寒冷地区混凝土坝老化主要表现在溶蚀、冻融和冻胀破坏、冲刷破坏等，其碳化深度不大。
By the computational method of carbonation depth, the carbonation depth and the carbonized time relations are obtained. The concrete carbonation depth according to the testing datum is forecasted.
由碳化深度的计算方法，得到了碳化深度与碳化时间的关系，根据实验数据对混凝土的碳化深度进行了预测。
