Study on Relationship of Seepage Field and Temperature Field in Sand Cylinder Experiment

摘要

Experiment on relationship of seepage field and temperature field was carried out in polymethyl methacrylate cylinder. In the experiment, temperature field was measured by high precision distributed optical fiber temperature sensor system (DTS) and seepage field was measured by piezometric tube. The results show that the relationship of the two fields is correlative, and a formula of the relationship of velocity of heat flow and Darcy seepage has been given out. In addition, hydraulic conductivity variation characteristics with temperature field has been analyzed.
