The　monitoring　method　of　the　prestress　construction　for　the　badminton　gymnasium　for　2008　Olympic　Games　is　introduced　in　detail.　The　calculation　of　simulating　prestressing　construction　is　carried　out.　In　general,　the　theoretical　analysis　and　measured　field　data　are　in　good　agreement.　The　rationality　and　correctness　of　computer　modelling　and　method　are　validated.　However　the　comparative　result　is　bigger　than　the　conventionally　acceptable　criteria.　It　is　argued　that　the　fabrication　and　installation　can　not　fully　made　ideally　according　to　the　design.　The　6%　loss　of　prestress　is　bigger　than　the　theoretical　value　of　2%.　By　use　of　the　deviation　results　of　the　prestress　loss　and　the　vertical　deformation　from　the　actually　measured　data,　the　research　data　which　match　the　measured　data　and　satisfied　with　the　acceptability　criteria　are　modified.
