摘　　要：针对西部软岩地区矿井建设采用人工冻结技术出现的冻结壁不交圈的问题,分析了传统冻结壁交圈判定方法在西部地区的不足之处,阐述采用冻结器纵向测温技术在冻结壁交圈判定中的作用。并结合实际工程,给出了纵向测温技术在检测冻结壁开窗部位、修复过程监测及判定冻结壁交圈的应用,明确了该技术在人工地层冻结法凿井中的重要应用意义。For the problem of un-closure of the frozen wall in the freezing shafts construction in western China, the disadvantages of the traditional methods in judging frozen wall closure is analyzed, and the effect of the longitudinal temperature measurement in judging frozen wall closure is expounded. In combination with the engineering practices,the application of the longitudinal temperature measurement on detecting the ＂window＂ in the frozen wall, monitoring the repairing process and judging the wall closure is introduced, and the significance of this method in freezing proiects is cleared.
