flood dike
5.Impermeable wall made up by mixing grout and dike fill can greatly enhance the flood-resistant ability of the exiting dam.
6.Spur dike shore protection project is designed for protection of the roadbed damaged by flood on Qingxi reach of Dongjiang River, the effect of which is calculated and analyzed by 2-D mathematical model, to confirm the stream-deflecting and shore-protecting effect, and determine whether the spur dike exerts any influence on navigation.
7.Through analyzing risk factors which influence the safety of levee, event tree model is constituted. The main invalidation codes for dike are researched from the angle of engineering geology. Be based upon three main invalidation types: flood, seepage and slip of levee, the risk computation model are founded correspondingly.
