0.1~0.3。
It is preferred that, the height of the concrete buttress structure is less than 100m.
The beneficial effects of the utility model：
The utility model is additionally arranged positioned at riverbed position concrete slab upstream side on the basis of conventional concrete panel
Concrete buttress structure, instead of profundal zone panel, reduce panel length；And part stockpile is instead of, so as to improve depth
Maintenanceability, improvement superelevation rock stress and deformations of concrete face slab and the dam deformation of pool panel, are high face dam or super
The construction of high face dam provides foundation, especially 300m grade high CFRD；Development for superelevation face dam provides support,
Promote ultra-high concrete panel rock-fill dams technological progress, be that the research of superelevation dam is accumulated experience.
