对渗流热监测理论各发展阶段特点与相关研究作了评述,着重介绍了定量研究阶段考虑渗流场影响推求温度分布的正演分析,详述了各渗流场与温度场耦合数学模型的基本原理、模拟对象、耦合机理与模型计算方法,总结了渗流-温度场耦合模型研究的趋势与问题。介绍了耦合模型计算的2个部分(渗流场计算与温度场计算)的研究现状与发展重点,阐述了研究基于非饱和渗流双场耦合的必要性和建立模型涉及的基本理论。对未来的研究提出几点建议:考虑有关参数的温变特性,提高模型仿真精度;开展基于非饱和渗流的耦合模型研究,丰富复杂条件下渗流热监测理论;加强由温度场求解渗流场的反演分析研究。

Abstract

Researches in the theory of monitoring seepage by measuring temperature are reviewed. Forward analysis on temperature distribution in consideration of seepage field’s effect in quantitative research stage are highlighted. Furthermore, the basic principles, objects of simulations, mechanism of coupling and calculation method of different mathematical models of seepage field and temperature field coupling are elaborated. A summary is also given on the trends and deficiencies of coupled modeling between seepage field and temperature field. The research status and development priorities of seepage calculation and temperature calculation are introduced. Moreover, the necessity of researching seepage-temperature field coupling on the basis of unsaturated seepage is presented, and the theory involved in the modeling is expounded. Some suggestions for future study are put forward: temperature variation of parameters should be taken into consideration to improve the accuracy of model simulation; coupled modeling based on unsaturated seepage could be researched to enrich this theory under complex conditions; and inverse analysis of seepage field with the assistance of temperature field could be strengthened.
