ABSTRACT
The stability of spur dyke directly affect the regulation effect of waterway and therefore how to choose more suitable structures and materials of the spur dyke become the concerns of many scholars. Though flume tests, firstly the stability problem of enrockment dams which are used frequently now by comparing the cross-section of the dam body type was researched, pointing out that the arc-shaped cross-section of the the dam body structure is more stable than the trapezoidal structure under the same flow conditions and obtaining the boundary conditions lead to water damage of enrockment spur dyke. Secondly, comparison and analysis research of the stability of the two new types of spur dyke (dam body is riprapping and dyke furface is concrete hinge; dyke body is riprapping and dyke furface is concrete and dry-laid pitched stones revetment) under different water level drops before and after groins in the flow conditions obtained above are given in this study and proposed that the size of drop water height is one of the restriction factor of dykes damage. It points out that these two new structure types of spur dyke has better stability than enrockment dams and problems should be noticeed in the engineering design which can be promoted and applied in practical engineering.
