季节冻土区由于每年有 1个冻融周期。在冬季 ,建筑物受到不同程度、不同方向的冻胀力的作用 ,往往造成破坏。从而我们力求寻找一些改变水工建筑物周围的温度场的措施来防止其冻胀破坏 ,在这里我们使用保温材料来达到防冻。 Seasonal permafrost area due to an annual freeze-thaw cycle. In winter, buildings are subject to frost heaving forces of varying degrees and directions, often causing damage. Therefore, we seek to find some measures to change the temperature field around the hydraulic structure to prevent the destruction of frost heave, where we use insulation to achieve antifreeze.
