Application of System Cluster Analysis in Leakage Analysis of Dyke
2009
Taking the case of Beijiang Dyke as an example,twenty-two water samples were collected for system cluster and stable isotope analysis.The result shows that the water samples of water gushing at 5m north to T9 borehole,T12 borehole and out-waters of drainage gallery north to T9 borehole are similar to the river water.In other words,they are great similar in values of δD,δ18O,Cl-concentration and TDS.So,5m north to T9 borehole,T12 borehole and out-waters of drainage gallery north to T9 borehole are recharged by river water and others are recharged by rainfall.Stable isotope analysis shows the same result.
