Abstract
The Environment isotope method and the artificial tracer method were used to investigate the reason of "piping" in Beijiang Dyke Shijiao section.According to the stable istope analysis of Deuterium and Oxygen-18 from the water samples during the flood sewn,the "piping" water origin was approved.Combining with the artificial tracer method,the leakage passage in the bedrock fault was determined finally.All results are very important to the next reinforcing the dyke work.
