%X Anchor basement is the key bearing component of suspension bridge;and its deformation and failure mechanism is the foundation of strength and stability evaluation.Several facts are found through the in-situ pull model test.The total displacement and the rate of residual displacement on the back anchor face show saddle and V-shaped distribution,respectively.The displacement of the surrounding rock on the flank appears plug-style distribution,and the rate of the permanent deformation is high.According to the numerical model test to be by fast Lagrangian analysis of continuum in 3D(FLAC3D),some conclusions are also drawn:(1) the stress field shows subsection character,and the stress transfer route between fore part and back part of the anchor body is different;(2) the plastic zones which appear plug-style are mainly found beside the anchor and in the upper rock mass;(3) tensile-shear complex failure maybe happen in the rock-anchor system.The plastic zones and the prominent deformation zones in the rock mass should be paid more attention during design and construction.
