摘要

摘要: 利用温度场连续分布监测成果反馈渗流场,能够克服传统渗流场点式监测的不足。通过实验室筑建均质土坝模型,并在模型内敷设分布式测温光纤及测压管等,同步获取渗流场与温度场信息。通过理论分析均质土坝温度场分布及变化与渗流梯度、水土温差、渗透系数、导热系数、比热以及时间等因素的关系,构建了均质土坝温度场反馈渗流场的数学模型,并进行了室内试验成果验证分析,实现了由温度场信息反馈渗流场信息。研究成果表明：土坝温度场信息推求渗流场信息是可行的,构建的土坝温度场反馈渗流场的数学模型是成立的。

Abstract: Through the feedback from the continuous distributed temperature field observed on seepage field, the deficiency of the traditional seepage field monitoring can be overcome. Based on an indoor homogeneous earth dam model built for experiment, with distributed fiber temperature sensors and piezometers arranged within the model, information of seepage filed and temperature filed can be obtained simultaneously. A mathematical model for the temporal and spatial distribution of the temperature field of the homogeneous earth dam is established after analyzing the following factors: temperature variation and seepage gradient, temperature difference between seepage water and soil, permeability coefficient, thermal conductivity, specific heat, time and so on. In view of the above, the seepage field is fed back. Using the experimental observation data of the model, coefficients of the mathematical model for earth dams are estimated, and information of the seepage field fed back from the temperature field can be achieved. The verification results show that the proposed mathematical model for the temperature field feeding back the seepage field is feasible, and that the mathematical model built for the seepage field fed back from the temperature field of earth dams is tenable.
