The problems of embankment dam engineering have already developed from single field research to two or more fields coupling (temperature field, seepage field and stress field). In order to realize the real-time full section monitoring and analysis for seepage condition, the article brings in coupling research about temperature field, seepage field and stress field and distributed optical fiber temperature strain measuring system. Based on analyzing its research background and demand, it discusses the progress in detail and put forward the research content and solving methods of key problems to guide the next research and test work.
