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

Table 9

Analysis of the influence of plate width on the pull-out force of underwater (single) sediments.

Blocked objects	Blockage height (m)	Blockage + water/overall height (m)	Blocked objects’ single-side area (m^2)	Blocked objects’ deadweight (kN)	Pull-out force of blockage (kN)	Pull-out force of blockage per unit width (kN/m)
