To　ensure　the　safety　of　constructing　the　north　anchorage　excavation　of　Fuma　Yangtze　River　Bridge,　an　extensive　instrumentation　program　was　carried　out　to　monitor　the　performance　of　the　excavation.　This　monitoring　effort　included　the　ground　movements　of　soil　outside　the　excavation　zone,　ground　movements　of　the　tops　of　piles,　lateral　deflections　of　piles,　and　prestress　in　cables.　Based　on　an　analysis　of　the　monitoring　data,　the　following　findings　were　obtained:　shallow　landslides　were　induced　by　rainfall　at　several　locations　outside　the　excavation　zone,　and　the　movement　directions　of　soil　were　consistent　with　the　natural　terrain.　The　horizontal　displacements　of　the　west　and　east　top　beams　were　generally　larger　than　that　of　the　north　side.　The　vertical　movements　of　the　tops　of　the　piles　exhibited　heave　initially　and　then　transitioned　into　settlement.　The　deflected　profiles　of　the　piles　were　similar,　and　the　maximum　lateral　pile　deflections　were　very　close.　The　measured　deformations　and　internal　forces　of　the　support　system　did　not　exceed　the　alarm　values,　which　suggested　that　the　excavation　was　in　a　stable　state.
