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

Table 11

Verification analysis of the pull-out force of underwater (mixed) silt.

Blocked objects	Measured value of blockage pull-out force (kN)				Calculated value of blockage pull-out force (kN)				Calculation error
	Blockage height (m)				Blockage height (m)				Blockage height (m)
