| 摘 要： | 根据测温孔和冻结器的纵向测温,提出采用灰色关联法进行数据分析.通过孔与孔的关联度计算来评价各冻结器的工作效果,确定薄弱的冻结器方位,然后根据关联度离差和总关联度随深度的变化,确定冻结壁在深度方向的薄弱环节.运用灰色关联分析对竖井冻结壁“窗口”事故实例进行了对照分析,验证了理论的实用性.

| Abstract: | According to longitude temperature supervision on freeze pipe and monitoring hole,put forward a new method called grey correlative to analyze the temperature data. The working effect of freezing pipe was evaluated by calculating the grey correlative degree (GCD), defined the location of the weaken freeze pipe. Besides, based on the change of deviation squares of GCD and total GCD with the depth, the weaken location of freezing wall was indicated along the shaft. A case of "window" accident of freezing wall was analyzed with GCD method, and the practical value was verified. |
