摘　　要：通过对不同含水量堆石坝土石体导热系数的实验测试,探讨土石体导热系数与含水量之间的关系,验证通过监测土石体温度场特性,用于渗流监测的可行性。并结合水布垭混凝土面板堆石坝周边缝分布式光纤光栅渗流监测实际应用成果,探讨环境量(气温、水温)、水位与探头温升的相关性;对疑似渗流区域的特性进行了分析。The relationship between the thermal conductivity of soil and rocks and the water content is determined by ex-perimental tests.The feasibility of applying temperature field monitoring to seepage monitoring in rockfill dams is veri-fied.Based on the practical seepage monitoring results of the distributed fiber grating sensor system in Shuibuya concrete face rockfill dam, influences of the environmental factors such as the air temperature, water temperature and water level on the sensor temperature rising are discussed.For probable seepage flow areas, the specific characteristics are ana-lyzed.
