The Dike Stability Analysis based on Strength Reduction Method

The dike engineering is an important part in the system of flood controlling. landslides is the main reason that leads to the dike break.In order to study the dike stability in an irrigation area, the dike slope stability is analyzed based on the strength reduction method and finite element method, and the safety factors of dike slope under the four typical calculation cases are calculated in this paper.The result shows that the dike is not steady under the rapid drawdown and it is steady under the othe cases,and the treatment measures should be taken to prevent severe disasters during flood. The research will provide a reliable basis for other similar engineering.
