土石坝渗流热监测技术研究

Study on Seepage Monitoring Technology with Temperature in Embankment Dam

对土石坝渗流热监测技术的基本原理、研究历史和现状进行了介绍,对土石坝的热学特性以及土石坝温度与渗流的关系等关键技术问题进行了讨论,并从理论上证明,利用分布式光纤量测得到的温度场,通过有限元数值计算,可以得到渗流场的渗透系数,实现对渗流场的监测。

After introducing the principle, study history and actualities of the technology, this article discusses such key problems as the thermodynamics characteristics and the relationships between temperature and seepage in embankment dam. It has been proved theoretically that the seepage monitoring can be realized by the finite element method（FEM）, if the thermal field obtained by the fibre-optics measuring method is given.
