摘　　要：针对地层冻结监测的应用环境,着重研究了分布式光纤温度传感器原理并设计了APD,建立一套适用于低温环境下的分布式光纤测温系统,以实现在冻结法施工中冻结温度壁的温度在线实时测量。为进一步设计适用于冻结法施工中的低温温度监测装置奠定坚实的基础,使得监测装置能更好地满足在低温条件下连续空间范围内的分布式实时温度监测,为冻结法施工的温度监测提供一种有效的手段。Aimed at the application condition of stratum freezing monitor, the article studies emphatically the principle of distributed optical fiber temperature sensor and designs the APD. And based on the study, a distributed optical fiber temperature measurement system （DOFT~） is set up for the lower temperature environment, which realizes the on-line real-time temperature measuring of the frozen wall in the frozen construction and sets up a base for further design of temperature monitor in lower temperature environment.
