Abstract: The instability of a Yangtze River levee was numerically evaluated with laboratory test results and historical data. The mechanical and physical differences of soil sample from crest, toe of the levee and from the bank of the river were evaluated. It is concluded that the hazards on the levee was caused by the differential settlement. The observed results are also in consistent with the numerical analysis results.
