| Abstract: | When using freezing method to cut shaft, it is important to learn the sensitivity of factors which affect the development of temperature field in artificial freezing soils for optimizing freezing scheme and dealing with critical situations. By analyzing data samples of the artificial frozen temperature field in the Huainan and Huaibei regions, a dynamic network that can forecast the temperature is formed which includes the overall elements that may affect the development of frozen soil temperature. After analyzing the network information, the sensitivity of every element is obtained. |
