基于原型观测的某拱坝施工期安全性态评价

Evaluation of Safety Behavior of an Arch Dam During Construction Based on Prototype Observation

碾压混凝土坝具有水泥用量少、施工速度快、施工工艺简单等优点,但也存在一些如开裂、层间渗水等影响大坝安全的问题。三河口拱坝是位于秦岭腹地的一座高碾压混凝土拱坝,其施工质量及大坝运行状态受到高度关注,本文基于施工期大坝原型观测资料,对三河口拱坝安全性态进行分析评价,为同类型拱坝设计和建设提供重要的指导及借鉴意义。

Roller-compacted concrete dams have the advantages of less cement consumption,fast construction speed,and simple construction technology,but there are also some problems such as cracking and interlayer water seepage that affect the safety of the dam.Sanhekou Arch Dam is a high roller compacted concrete arch dam located in the hinterland of Qinling Mountains,and its construction quality and dam operation status have attracted great attention.Based on the observation data of the dam prototype during the construction period,this paper analyzes and evaluates the safety performance of the Sanhekou arch dam,which provides important guidance and reference for the design and construction of the same type of arch dam.
