摘　　要：基坑和水坝等工程发生渗漏会带来极大的安全隐患,渗漏引起工程破坏是一个缓慢变化的过程,需要长期的实时监测。对温度变化进行监测是研究渗漏的有效手段,分布式光纤测温能监测整个监测区域的温度变化,克服了传统的测温手段只能获得分散点的温度信息的缺点。在新疆乌鲁木齐河的河床上采用分布式光纤测温的方式监测注水后不同土层的温度变化情况,该试验表明分布式光纤测温是一种理想的渗漏监测手段。The leakage which occurs in the engineering such as foundation and dam would bring substan- tial security risks, and it is a slow change process, requires long-term real-time monitoring. Temperature change monitoring is an effective means to study leakage, and the distributed optical fiber temperature measurement can monitor the temperature change in entire monitoring region, and overcome the disadvan- tages of traditional temperature measurement means with only obtaining the temperature information of the scattered points. Different soil temperature change is monitored by the way of distributed optical fiber temperature monitoring water after tests in the riverbed of Urumqi River, and it shows that the distributed optical fiber temperature measurement is an ideal means of leakage monitoring.
