STABILITY ANALYSIS OF THE GRAVITY ANCHORAGE OF A SUSPENSION BRIDGE BASED ON LARGE-SCALE FIELD TESTS


 The stability of gravity anchorages is critical to the safe operation suspension bridges. purpose this paper study a anchorage under tension main cables. Large-scale load tests and direct shear nature state saturated were carried out in adit at bottom anchorage, because surface below design water level reservoir be built. Representative rock samples area selected for indoor tests. basic parameters mass characteristic value subsoil bearing capacity obtained based on field results. static theory was used calculate anti-sliding coefficient, anti- overturning coefficient contact stress anchorage. finite element software horizontal displacement, vertical settlement calculation results met relevant requirements, it can considered that stable It would provide reference bridges.
