Problems about Design of Dyke Reinforcement

The dyke experiences very high flood level more and more frequently. The timely issued " The Standard of Dyke Design" has played an important role in the design, measure feasibility study and examination of dyke reinforcement. Safety appraisal is required before dyke reinforcement design. But, the conducted item is safety demonstration in the process of dyke reinforcement design at present. This paper suggests that at least 8 aspects should be considered in safety demonstration. The effective water head is considered as the most important factor for dyke safety and reinforcement design. Seepage control measure design is an important part of dyke reinforcement design. Its correct train of thought is discussed in this paper. Some other factors for dyke reinforcement design are also pointed out.
