Model Test Research on the Influence of Gate Blocking in Siltation Environment

Table 10

Analysis of the influence of the height of underwater (mixed) silt.

Blocked objects	Pull-out force of blockage (kN)				Pull-out force of blockage per unit width (kN/m)				Silt increment per unit width at intervals of 0.1 (m) corresponds to the increment of force (kN/m)
	Blockage height (m)				Blockage height (m)				Blockage height (m)
