The anti-crack concrete pier column in the extreme environment of the alpine region comprises a hollow pier column body, an outer wrapping layer is arranged on the outer surface of a main body structure of the hollow pier column body, and a lining layer is arranged on the inner surface of the main body structure of the hollow pier column body. The outer wrapping layer comprises a water storage material layer, a water retention material layer and a light reflecting material layer which are sequentially arranged from inside to outside. The concrete pier column can be effectively prevented from cracking under the action of a large-gradient temperature field and a large-gradient humidity field in an alpine region. 本实用新型公开了一种高寒地区极端环境下抗裂混凝土墩柱，包括中空的空心墩柱，所述空心墩柱的主体结构外表面设置有外包层，所述空心墩柱的主体结构内表面设置有内衬层，所述外包层包括自内而外依次设置的蓄水性材料层、保水材料层和反光材料层。本实用新型可以有效防止混凝土墩柱在高寒地区大梯度的温度场、湿度场作用下开裂。
