Therefore, the evaluation of the quality of river bank construction is essential. The paper develops an evaluation method by giving the marks for some criteria such as the risk of the actual condition of river bank construction, the aftermath of the potential accident in consideration to statical and dynamical parameters. The result is used to grade the risks, which is the basis for defining the level of structural safety. The developed method has been applied to evaluate the quality of right side bank of Chu river (from Km38+700 to Km39+300), which is located in Thieu Tam village, Thieu Hoa district, Thanh Hoa province. The evaluation result shows the score P = 270,25, which is equal to level 1 of the structural safety. This result means the river bank construction is being at high-risk condition, therefore a solution to ensure the safety of the river bank construction is proposed accordingly.
