By means of lab and in-situ rock mechanics test, establishment of E-Vp relation, engineering rock mass classification, computer simulation test and back analysis of shiplock slope displacements, the rock mass deformation parameters of unload zone in the TOP shiplock slope are studied. The relationships between rock mass deformation moduli and rock sizes are established. The study results show that macro-mechanics parameters of rock masses of the TOP shiplock slope are of obvious size-effect.
