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

Table 13

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
