Based on model test and numerical simulation

the research on displacement of a gravity anchorage of a suspension bridge has been carried out. The model test is carried out with geometrical scale 1:100 and soil mass force scale 1:1.325. Numerical simulation adopts the same conditions of the model test. The Mohr-Coulomb yield criterion is used for soil. Anchorage and pit-supporting structure are regarded as elastic mass. Parameters are chosen according to the similar material of the model test. The research gives the displacements of anchorage under different load conditions. For the designing load

it is shown that the anchorage itself has horizontal displacement and rigid rotation with forepart sinking and back-end heaving. Displacement increase with the designing load added. In addition

the soil improvement

pit-supporting structure and surrounding soil mass contribute greatly to the stability of the bridge anchorage.
