摘要
简要介绍了在二滩拱坝1998年5月初次蓄水期,通过拱坝垂线和监测网系统,用统计模型和确定性模型理论分析方法,建立了施加于坝体各作用量与坝体受作用后的效应量(变位)间的数学关系;并根据预先计算分析成果,提出了在初次蓄水运行中拱坝变位的参考预报值,实时对二滩拱坝实际工作状态作出安全评判。
This paper presents that during the first impoundment of Ertan reservoir in May 1998, mathematic relationship between the loads acting on the dam & the respondent displacements was established by use of statistic model & determined model theoretic analysis method based on the observation results of the plumblines installed in the dam & monitoring network surveying results. Based on previous calculation & analyis results the dam displacement predictive values during the fist impoundment operation were given & Ertam arch dam actual operation was judged safe.
