摘要：

An experimental investigation is conducted for comparative study on traction performance of grouser shapes on an extremely soft seabed. Two kinds of grouser shapes are investigated with 18 grouser models consisting of 9 triangular types and 9 blade types. The grouser span is kept constant. Cohesive soil of seabed is modeled by means of benthonite-water mixture. Sinkage and traction forces are evaluated for each grouser model with respect to changes of relative bearing pressure to the residual shear strength of soil and shearing velocity.
