Let the single-layer water-filled film pouch 3 be high with a constant value h=0.22m.
1. Unit width side-to-side clean water pressure P Static state was calculated:
P1 Static state ＝1/2γ(H-3h)2＝0.5×9800×(0.8-0.66)2＝96.04(N/m)
P2 Static state ＝1/2γ(H-2h)2-P1＝0.5×9800×(0.8-0.44)2-96.04＝539(N/m)
P3 Static state ＝1/2γ(H-h)2-P1-P2＝0.5×9800×(0.8-0.22)2-96.04-539＝1013.32(N/m)
P4 Static state ＝1/2γH2-P1-P2-P3＝0.5×9800×0.82-96.04-539-1013.32＝1487.64(N/m)

3. Anti-slip safety coefficient K estimation:
Let anti-slip safety coefficient = maximum frictional resistance of single water filled membrane bag bottom/total lateral water pressure of single water filled membrane bag.
Considering that water possibly exists between the water-filled membrane bags, the conservation value mu=0.3 of the friction coefficient of the polyvinyl chloride is adopted between the water-filled membrane bags, and the friction coefficient between the water-filled membrane bags and the foaming impermeable bottom plate is adopted to be mu 2 =0.4.
Considering the case that the water filling film bag is not full of water,
It self-resets to g=γ×0.8×v Bag(s) =9800×0.8× (1.8×2.5×0.22) = 7761.6 (N/m)
f1＝μG＝2328.48(N/m)f2＝2μG＝4656.96(N/m)
f3＝3μG＝6985.44(N/m)f4＝4μ2G＝12418.56(N/m)
K1＝f1/(P Water and its preparation method 1×L)＝7.22
K2＝f2/[(P Water and its preparation method 1+P Water and its preparation method 2)×L]＝2.75
K3＝f3/[(P Water and its preparation method 1+P Water and its preparation method 2+P Water and its preparation method 3)×L]＝1.65
K4＝f4/[(P Water and its preparation method 1+P Water and its preparation method 2+P Water and its preparation method 3+P Water and its preparation method 4)×L]＝1.56
Considering that the friction coefficient between the foaming seepage-proof bottom plate and the dykes is larger, the integral anti-slip stability of the structure does not need to be checked.
(V Bag(s) -volume of single water-filled film bag, L-width of upstream surface of single water-filled film bag)
F 1、f2、f3、f4 -the friction force exerted by a single water-filled film bag bottom consisting of a top layer, a second layer, a third layer and a bottom layer in sequence
K 1、K2、K3、K4 -the safety coefficient of the water filling film bag of the top layer, the second layer, the third layer and the bottom layer in sequence
According to the calculation, in the ultra-high flood range (0.8 m), the water retaining sub-dike is higher than the flood still water level by the height h (0.22 m) of the water filling film bag 3, so that the structure of the invention is stable, and meanwhile, the wind and waves higher than the still water level can be blocked.
